  1. 1. KääntäjäHexagon Among other things, the saddle is needed to remove the Allen key. Thereare many different sizes of hex wrenches for various screw. It may be useful tobuy a kit that contains a number of keys to different maintenance situationsthere is always the key to the required size. On the other hand, if you onlyneed one or two sizes (such as 4 and 5 mm), can be järkevänpää focus on qualityrather than quantity.Torx keys Allen wrenches similar to a Torx keys are often needed mm. brake discmounting bolts.Cross and screwdriver Screw Drivers should be more sizes and shapes, because the screws thereare many types. In particular, the cross head is worth noting that there are twotypes of commonly used (in addition to sizes); Pozidriv (PZ) and Phillips (PH).Although they look similar from a distance, they are not compatible with eachother. In an emergency, often even in doing wrong, but it often causes damage tothe screw. Among other things, therefore, the wheels should be used with anAllen or Torx screws.Spanner / wrench set Wrench to tighten the nuts and ways to loosen the tools. Different sizesof nuts have their own wrenches. Keys come in many shapes, especially the nutfrom all angles catchy ring spanner is a good työkalu.Sitä not, however, oftencan be used, for example, pedal removal. You should find those having ordinaryjaw at the other end. Sizes of 8, 10, 13, 15 and 17 mm is needed most.Preferably a couple of pieces each.Socket wrench / ratchet wrench set The key is used ratchet wrench and lenkkiavaimien way to open andtighten the nuts. Ratchet wrench is available in many different sizes of nutsfor cores. The bottom photo with the ratchet set is a handy acquisition,including the actual ratchet sockets in addition to several sizes. Ratchetwrench provides high torque and socket grips the nut firmly on each side, so themore tightly the nut will open easily.Kartioavain Such as a wrench, but thinner so that it matches the wheel hub, the coneopening better than thicker wrench. Most of the cones open keys whose opening is14 or 15 mm. You should find out as soon as the key pair with thesekitaleveydet.Pump Bicycle maintenance is a very important tool in the wheel pump to fillcompletely exhausted tires. The pumps are available in a variety of nozzles fora variety of valves.Valves The store is always a good idea to have a few inexpensive safety valve.Rubber repair kit The patch set includes rubber normally liimatuubi, rasp, a few differentsize of the place, and in many cases the operators manual.
  2. 2. Plastics ring In general, the tire can change hands, but is needed between the plasticrengasrautoja or plastic ring to the outer ring may be out of the rim. Back tothe rim, it usually gets on your hands.Oil Bottle A bottle of oil is a necessity for the wheel being serviced. Oil qualityis different and their suitability for different applications has been a lot ofopinions. Consensus-a consensus on one thing - canola oil is not suitable foryour bike!Thread Cutting Tool Chain can be lengthened or shortened by cutting it with the specialtool. Removing the chain wheel / Attaching the wheel will also require cuttingtool unless the chain is the quick coupler.Puolausavain Surfaces may become loose over time. Puolausavaimella they be tightenedwhen the ring rotates directly. If the ring is already in, or in connection withthe tightening of the spokes of the so-called. throwing, it can straightenrihtaamalla, which requires a little bit of practice. The alignment spokeslocally loosened from the side, where the band throws and accordingly tightenedon the other side.Strollers removal tool designed for Strollers are often needed to remove the special tool or more. These areof many kinds. Modern cassette deck is required to remove the lock ring tool anda chain whip. Threaded pack can be removed only circlip tool, which is slightlydifferent than kasettipakkaan suitable. Shimano Centerlock brake discs will beopened and attached to the cassette deck tool.Various small brushes and suteja Chain and sprockets are easier to clean if you have a small brush. Tire pumping Prepare the working environment suitable blank. Open the valve cap and put it in a safe place for recovery. Turn the wheel until the valve is at the top. Set the pump to the valve on the mouth, supported by the edge of the rimwith your thumb and start pumping. Pump the tire to full and put the valve cap back on.There are a few different types of valves. The most common is the so-called.Quick valve, as found in most of the bikes. If the valve is, however, differsfrom the traditional may be that the pump is not able to directly pump the air
  3. 3. from the tire. In this case, a separate adapter piece between the pump and thevalve (for example, adapter socket screw thread of the valve and then pumpingtakes place in the normal way). Ask this example, the bike shop from expertstaff.They must figure below traditional. Missing from the picture narrow metalmounting ring, or just a nut, a valve is closed rim. Valve and the black plasticcap in the middle of the metal sleeve to prevent air from escaping through thevalve out of the ring. Ring can be emptied for maintenance work, for example byloosening the sleeve enough. Loosen the caliper mounting screws using an Allen key enough, turn the screwcounter-clockwise, so that you can move the saddle up or down. If necessary,turn the saddle to the right and to the left while lifting or lowering it.Mounting screw holding the lever in some wheels that turn the saddle mount getsloosened without tools Raise or lower the seat height. Make sure that the seat is level. Tightenthe saddle screw, turn the screw clockwise or turn the lever tight enough so thesaddle does not move while driving.The saddle is the right height when you are pedaling leg can straighten thepedal is at the lowest point, but one extends very pedal.PLEASE NOTE THAT THE seat tube, seat tube HEIGHT BRAND upper must not be lifted.Seat tube must be sufficiently BODY inside the tube!Bicycle Maintenance and Repair / Lock Oiling<Bicycle Maintenance and RepairJump to: navigation, searchIt is a lock, but not its use.Oiling the lock is not ostensibly as no surprise. However, it raises worthmentioning a pitfall. The lock is not put into the non-locking or snap-melt oil(Gun oil is apparently quite the same as the lock oil). In particular, chainoil, or "universal oil" should not be used.The reason for this is the fact that the lock mechanism is rather tight. The oilhas a habit of "pikeentyä" period of time when the lock mechanism hangs (stuckin the side plates). Different fats repetitive lock and also tend to collect inaddition to the extra dirt.Slowly working or winter will freeze the lock should put a lock oil. Slownessand freezing can be prevented by working proactively for example, in the autumn.Completely jammed the lock may try to open one of the solvent (eg, crc, wd-40)but it would not necessarily särkemättä open again.
  4. 4. Bicycle Maintenance and Repair / rubber patches<Bicycle Maintenance and RepairJump to: navigation, searchThe following is a step by step instructions for patching the outbreak ofrubber. In the example, the rear tire rubber patch up the hard way, but withless can get. Workflow is similar to the case of the front tire.In general, positions can be adjusted in such a way that leaves the tire ontothe wheel and takes only a hole in the tire off the rim. Hole, however, oftencan be found just by listening to where on the hisses.The fastest way to do the job equipped with a quick release wheel is to changethe inner ring and the paikkoa then erupted with time. So, one should keep inintact rings in stock.The instructions are applicable mainly to all the wheels, only the tire removaland mounting is slightly different, depending on the mounting method and thegearbox.The necessary toolsIn most cases, stoked survives without actual tools, ie the place the contentsof the series (place, "glue", and sand paper) are sufficient. In addition, ofcourse, some type of pump is required. Pump Rubber repair kit Ring Hardware Kit (makes it much easier removal of a tire / rim laittoa) Indian ink If the ring is removable so for some reason (not pikalinkulliseen) boltedonto the right size wrench (15mm) or a set of ratchet (or wrench). In addition,if necessary, a screwdriver (for the screws, not the direction of the rim atall!) Bucket of waterRubber patchesRear tire mounting screws have been removed, and the tire lifted partially outof the back of the fork slot. Mounting screw must be removed in addition to thegray intermediate parts which leave the shaft by pulling.STEP 1 - Work EnvironmentFirst of all, prepare yourself a good working environment. The spacious interiorof the flat terrain or outdoors, with all the necessary facilities are readilyavailable. Protect your saddle and handlebar for example by pulling the ends ofthe plastic bag, etc on top of them. Turn the wheel over so that it is in thecountry of the saddle and the control rods. This bike is easy to maintain, andthe ring may snap out of it.STEP 2 - Tire RemovalLoosen and remove the tire mounting nuts spanner or wrench. Some bikes ring maybe attached to the Allen bolt. See, the key can not rotate around an empty nutas this will quickly nut corners round. Such a nut is difficult to remove. Putthe removed screws and other small parts recovered, so you do not lose them, andyou still get piled on the wheel! If you disconnect the rear wheel, open the
  5. 5. jarrukäpälän screw so that you can hoist ring out of the swing arm.When these bolts are removed, you can lift the tire out of the back of the forkthe slots. Chain leaves generally easy gear around. If it is the hub of thewheel speed and remove the rear tire, be careful not to damage the cables. Thecable is not the reason to remove the ring. If the ring is still air left, emptyit at this point.The outer and inner rubber rim around disconnected.STEP 3 - Exterior and interior Removing the rubber rimNext, the need to get the tube out. Start by removing the valve. First, removethe valve cap and the black turning, followed by one or more of the metalmounting ring around the valve off. In some models, the valve is just a blackradome. Empty leaves rubber outer rim generally quite easily by lifting theouter edge of the rubber band to the exterior. If necessary, can be used to helpeven the blunt end of the wrench (or rengasrautoja), which pushes the outer edgeof the rubber and the rim and pushes the outer rubber. When the outer rubber hasa second edge outside the rim, leaving it quite easy to remove. Usually alsocomes with a rubber lining (please note that the valve is pressed through thehole in the rim, so that the interior rubber gets loose). Treat the inside ofthe rubber gently, for example, sharp tools can make it more holes.At this point, it is good to check the external and internal condition of therubber visually. If ulkokumissa has large cracks or holes, you may want tochange it at the same time a new one. Similarly, if the tube seems completelycorroded, may be wiser to change the place of a whole new rubber.Sisuskumista locating hole.STEP 4 - hole location and position of theIf any sharp and thin has made a hole into the rubber, it can be difficult todetect with the naked eye. A clever trick is to use a bucket of water with help.Attach the valve back to the inner tube and pump it some air. Then immerse therubber water container (or such a big part as it can hold at one time). Visitthe entire inner tube through this way. You can also squeeze gently add pressureon the rubber ring and a clearer view of the leak. Leak point to identify futurebubbles around it. Once the hole has been found, for example, felt-tip pen tomark it for further processing.Rubber seats successfully repair kit with the included tools. Take first a smallmetallic rasp and sand the hole in the rough environment. This glue stick andplace the rubber better. Next, take a small liimatuubi and apply a smooth, thinlayer of glue roughened area. Places of different sizes - abrade and applyadhesive to the entire site within an area. Let the glue dry for a moment sothat it does not stick to your finger when touched. Then, take the necessarysize of the place and remove the foil screen is bright. Press the foil againstthe surface was over the hole and squeeze the current position firmly againstthe rubber. In general, the place gets liimaantua rubber in minutes. Finally,remove the on-site plastic film. Rubber has been patched!Below is a series of pictures of the hole in the rubber patching. Grind thefirst rasp hole rough environment (Fig. 1). Then apply a thin and even layer ofadhesive on an area of ??size (Fig. 2). Take off the shiny foil screen position(Fig. 3), and press it firmly over the hole (Fig. 4).Kuminkarhennusraspilla.jpg Liimanlevittaminenkumiin.jpg Kuminpaikka.jpgPaikkakumiin.jpg
  6. 6. Place the wheel / inner tube into the rubber in first on one side and onprogress around the ring. May need something to help blunt object.STEP 5 - Indoor and outdoor putting the rubber back onto the rimStart rubbers in place by pushing the illegal rubber valve inside the rim of thehole and tighten it to the rim, a narrow clamping ring. Some valves have no suchtension ring, it is therefore sufficient to insert the valve through the hole inthe rim. See the inside of the rubber rotate the wheel straight, and it does notgo to the thread at any point. Pump sisuskumiin little air, if necessary, sothat it seals around the rim, and holds it there. Place the rim and the insideof the tube into the rubber inside, starting from one side and moving slowlyaround the entire ring. At this point, care must be taken so as not to damagethe inner tube. Different ways to have a definite number, but it is worth tryingto get the tube into the rubber inside and then go outside to put the rubberedges of the edges of the inside of the rim. At the end you will probably usetools such as a wrench blunt end (or rengasrautoja) kammetaksesi rubber outeredge of the rim on the inside. Note that at this point you will probably need toclear the inner tube completely from the air, so you get to go to the outerrubber in place!When the outer rubber is all over the edges of the rim inside the tire pumpedfull of air, so you can see it leaking (I hope not!). If the air seems to remainin the ring, you can go to the next step.Putting in place the tire on the rear chain.STEP 6 - Mounting the tire on the rear chainTyre put back in the same way as the wheel was taken out, but in reverse order.Lift the ring in place, put a chain around the sprocket and the chain lower thering into the slots. Remember any spacers between the fork and the nut! Finally,tighten the ring screws tight enough to wrench or socket wrench. Do not forgetto pay attention to the correct place, as well as possible jarrukäpälää ashifting frame holders.Tighten the ring screws alternately and make sure that the tire should bestraight. This sees Rotate the wheel and looking straight throwing it rotatesfrom side to side. When the ring is in place, tighten the screws on the end of asufficiently tight.Finally, turn the wheel over, and test run before you go further. Every serviceshould also be lubricated bearings, sprockets and chain, and to ensure that allnuts and bolts are tight. Paineputsaus waterOne clever way to clean out the chain is to wash it with a hose (pressure) or apressure washer. This gets to be too hard in the dirt out of it. Be careful notto greasy Moska fly braking surfaces. Beware of the bearings.To pressurize the water is injected, preferably the wheel in the longitudinal orvertical axis, wherein the bearings will not go water. Kura goes really well sothe chain links of the inner surfaces.Dry scratching
  7. 7. Reasonable conclusion can be reached just by looking at the scratch off excesswith a dish brush. The result can be finished with oiled cloth. The device ofthe chain around the cloth and rotating the crank arm so that the chain runsbetween the rag.DissolventsAll sorts of tricks can be found, biodegradable detergents bensaan car and lampoil. These are the more laborious tricks.Detergent oil soap and are less toxic than solvents. However, the condition of asolvent to clean faster and more thoroughly.Chain cleaning is also a special washing equipment, which is placed indetergent. The device is placed downstream of the chain around the chain withthe chain on the wheel in place. Then, just rotate the crank arm, so that thechain runs through the device. Your machine has rotating brushes putsaavat chainquite thoroughly.KMC chain Manufacturer does not recommend solvent cleaning or washing facilitiesfor the use of the chain. [1]LubricationVarious oils and waxes can be found.Generally, a compromise is sought with respect to the chain to adhere to the oiland the amount of garbage as the oil sticks to the chain and thereby closed.Chains should be regarded above all oiled and not rusting. If continuous OILINGdoes not like, is mainly an alternative to a tougher trade. Especially in thewinter rain mud keleissä no options For tough oils are hardly any.Ketjuvahat are good alternatives to conventional oils because they do not justcollect dirt chain. Prior to the use of the wax should be removed completely andwash chains in some solvent-based, so that all the old or the storage of oil andgrease can be removed. Waxes are good kurakeleillä.Mountain Bike Action magazine had also recommended chain oil from the mostflattest synthetic car engine oil. In the evening cleaned up dirt from the chainand the oil is placed in a chain. In the morning, before leaving wiped with acloth to remove excess oil.Thin Teflon lubricating oils (eg, TF-2) are also suitable, but they will have toput every day, because these oils are not strong enough for heavy consumption.The wires are different grades and different rates.Perusvaijerit are normally braided wires. It is now available in addition to theso-called. smooth (the slick wire) wires (e.g. Jag wire) whose surface is verysmooth. The wire runs really flatter shell and not get stuck very easily, evenif the cable and insert there would be a thin mud. Furthermore, it is alsoavailable in a teflon-coated wires. Teflon to reduce friction when the wire ismoving swiftly cortex.Is not the same kind of shells are used with cables. It always pays to choosethe shell with Teflon inner tube. In this case, the wire of the oil is, inessence, that a couple of times a year öljyrätillä disconnected the cable ispulled clean. Teflon lining to help, even if the wire is a sharp turn.Wires has in practice (at least) three different types of head (various
  8. 8. locations suitable for the wires, the handle end of the act): Shift (cross-sectional or longitudinal direction of the cylindrical head,less than the brake cables) Road bike brake cable (longitudinal end) Mountain bike brake cable (transverse cylindrical end)The wires are sold in addition to a variety of lengths. Going to the rearderailleur cable is the longest. For example, a normal 56-size road wheel maynot be sufficient 180cm long cable. Tandem learning is usually not enough eithernormal rear brake cable. If the cable length is not enough to be reliablyconnected in a two wire, in which the wire passes through the free (without thecover). Note: the front before connecting the cable must be threaded into place.Connection can be made in an emergency by making, for example, a sailor knot,but the connection is in any case advisable to check with one or two smallconcertina squeezable tube stage.Brake cables are thicker than the gear cables.Wire cutting and tying the headWire cutting there own pihtinsä, the use of which is highly recommended.Ordinary pliers and linjapihdeillä with a cutting edge, then youre successful,as long as to make sure that the blade is thick enough for metallilangalle.End of the cable may be small crimp the ends of the head is not going fraying.These ready to be placed at the ends of the wire "sheaths" are aluminum, but forthe same purpose is also the old or the new wheel finishes for nipples.The wire tensionThe cable is tensioned correctly (or length) is very critical, especially in thetransmission. More on this side of the gearbox. V-brakesMake sure that you are buying the correct type of brake pads, you may need apiece of the old model. Remove the second jarrulänkeen adhesive metallic outercasing complicated Press jarrulänkiä at each other and through the complex outof place. Remove the brake pad retaining clip nut (often the Allen bolt from thebrake pad pin). Checking the order in which the logic and jarrulängen both sidesof the washers are of different shapes. Convex and concave discs designed tooffer a bit of adjustment. Remove the old washer off and install a new pieceinto place accordingly. Make sure that the piece goes to the correct direction,usually a piece of the side of the rim is marked with the direction of rotationarrow.Adjust the brake pad so that the brake is pressed, the brake pad hits the centerof the rim braking surface perpendicularly. Brake lining the front edge of thewheel rim should be taken before a piece of the rear edge of the front of therim, in adopting the closed rear edge is about 1 mm from wheel. Tighten the shoenut (this may require more undertakings as brake pad tends to turn when the nutis tightened, therefore, be very attached to a piece of tightening it). Repeatto the other piece of the same thing. In particular, check that the piece hitthe side of the tire during braking, so as not to puncture.Adjusting Wire: Often with new pieces jarrulänget remain farther, because theold worn pieces puristuivat them closer together. This leads to the brake cableis loosened, if the goal is the same handle business from the old pieces. Startby turning the brake lever found on the adjustment screw inside the handle aspossible. Set screw consists of a screw and self-locking nut, first loosen thelock nut, turn the screw in the handle and tighten the lock nut. By turning the
  9. 9. adjustment screw in the handle for the wire rope tension can afford, which isrequired when the brake pads wear. Check that the brake cable covers aresecurely in place, also at the start by removing the complicated place. Run thewire tension generous adjustment by changing the point at which the wire istightened jarrulänkeen. So, loosen the clamping nut / bolt and loosen / tightenthe wire and tighten the nut / bolt back. Fine adjustment can be carried outhandle screw.At the same time, when you change the brake pads, you should also clean the wireand oiled it lightly. In winter you can use the car oiling locks used to lockmelt if the wires tend to freeze. Add ropes.The other half of the rim lagsSometimes it happens that when the brakes jumahtaa the other side of the wheelrim, or handle moved by the other side.Basically, the brake control can be adjusted on both sides of the adjustmentscrews (centering screws). These not only usually need (or should) cover: - abetter bet is to address the more general cause of the fault. So, oil brakepivot, or better yet, the first joint of the cleaning and then oil. If this doesnot work then only to be adjusted. Oil in the same cable.Disc brakesDisc brakes have a wide variety. It should be noted that in many cases it is noteven from the same manufacturer in different models do not use the same brakepads. For example, pieces of equipment manufacturing Kool stop to the catalog ofthis writing 46 erimallista returns [1]. The various pieces of the brakes ischanged in various ways.Common, however, it is probably that the fire exchange is quick and easycompared to the wheel brakes.Disc brakes must also remember that the pieces (or plates) shall be dischargedoil. Pieces of perishable finally, the disc can be cleaned if the pieces did notmake it öljyyntyä.Avid BB7Avid BB7 mechanical model brakes pads changed as follows (no tools needed): disconnected disk (ring) rotated the brakes on both sides of the quick adjustment screws fully open turning a small piece may be diverted into the old out (with fingers) when the two pieces are not come completely off between the pieces of themetal insert (springs) out of the put new pads in place (like the old) careers put a piece of string between them (career) puck back Finally, in such a way that cuts down the brake works as desired (eachindividually quick adjustments so that the piece almost touching the plate butdoes not drag on, as close as possible).The job is quite simple and does not require the same kind of "applying" thewheel brakes. Cuts corners can not and need to be adjusted changing. None of the(hex, etc) on the screw does not need to be touched. Wire does not need to betouched.
  10. 10. Hub bearing is usually attached to the axis of the cone and the hub of thebearing cup through a slot in the ball bearings (other types are very rare).The bearing is inspected, cleaned and greased regularly.The hub must not be hand-substantial slack, but on the other hand, it mustrotate easily.Before landing, look for an exploded view of the hub, you will see the parts andtheir order.Navan unloading and stackingKartioavaimia.Cones open kartioavaimella.Navan cones are locked onto the shaft nut (= standard nut). The package isopened by opening the nuts.Cones, hub bearings keep the balls in place, or they will fall when the conesremoved. On plugging it may not stay in place when you put the hub suitably fat.The hub must not be hand-substantial slack, but on the other hand, it mustrotate easily. Thus, to obtain precise torque is not quite easy and does notsucceed every time on the first try as a professional. However, since it is theonly nuts so that will work in the end and does not in itself is not difficult,just tedious.All the hub parts are subject to wear in the long run, of course, but properlytuned very long-lived.Normal dimensions of the hubTerrible generalization: Fork width 100mm. Rear Fork (10-8 speed) 135mm. 7-speed130 or 135mm.Shaft diameter is generally harder for 9mm but gets thicker.The polesThe different shapes of the poles is a ferocious rate.Find your hands on your belly exploded view, you will see the parts and theirorder.Cones are the different models of the different poles.The use of various polar axes (length, thickness, threads, ...)Poles have a wide range of ball bearings.Rear wheel Ketjuvaihteisen is a particular nuisance, it is also that the hub andfreewheel sprocket mounting. Connections should be different.In addition, the terminals may be other differences.Nestevälitteisten or hydraulic wheel-disc brakes and bleed the manufacturersinstructions.In general, the work needed to manufacturer or model-specific expression of a
  11. 11. series, which consists of the brake caliper matching terminals and usually aplastic tube and a syringe or container. In addition, tools are needed to openthe expansion tank.Slurry and increasing the need for brake fluid suitable liquids. Brake fluid isa wide range of bicycle brakes. For example, manufacturers of Magura and Shimanouse of mineral oil while in use, for example Hope Dot-4 liquid (car brakefluid). These are not interchangeable, and using the wrong fluid can ruin thebrake lever or brake piston seals or the time to get up to burns.Brake pads and rim jarrulevyineen is a good time to vent removed even if thefluid is not properly vented, should not have to brake surfaces can splash it byaccident, or to grab the hands of the brake disc surface, for example, where itis easily transferred to the brake pads. Oiled brake pads do not like.The trip computer is a bicycle connected to an electronic device that measuresand displays the rider on the model, depending on the current speed, distancetraveled and time elapsed, peak and average speed and total distance, and time.Other activities may include kalorimittari, tire speed measurement, andespecially high-end models, heart rate and elevation.Between the different functions you move in a simple interface and a few,usually only two buttons.Computer attached to a wheel on the handlebars a small stand, when the computeris able to take the wheel at all times when leaving the house.Performing the measurement sensor is placed close to the normal to the frontfork spokes. Magnet, the sensor will react with the sensor attached to a spokeon the same date with the screw. The sensor and the magnet, the distance shouldbe approximately 3 mm. The sensor and magnet must be kept clean so that mudaccumulated dirt does not affect too much the magnetic field, the sensor can notregister the tire rotation
