How To Get A Cable Line Installed

I of the bug with using metallic cables to control bicycle transmissions is that the  weather does its best to ruin them, with water to cause rust and dirt to gum everything upwardly. If well looked after, gear cables can last years just if you leave them to the conditions, you could be plumbing equipment replacements oft, which isn't cheap. If corrosion has got the amend of one of your gear cables, here's how to replace it.

Our guide beneath shows you what we believe is the best method to refit a gear cable in a SRAM Rival hydraulic road restriction/gear lever.  We've included a list of the tools and materials that y'all will need to complete the task and in some cases where you tin buy them. If there are others that y'all adopt so feel gratis to allow everybody know in the comments.

Tools & Materials

New cable

Cable cutters

Allen keys

Plumbing equipment a new gear cable should be pretty unproblematic, just modern bikes with internal routing and convoluted cable runs through the components and frame can make what used to be a 5 minute job take a fleck longer. For example, frames with internally routed cables can require removal of the cranks and bottom subclass equally is the case with the bike in our example below.

Be methodical and don't be afraid to to have the long route. Some of the fuzzy logic used past the component manufacturers means some of the simple steps, similar threading the new inner cablevision through the shifter mechanism, is a pain unless you take the shifter off the bars. And then, deep breath and permit'southward fit this new rear gear cablevision.

1 Unfasten the old cable Fully downward shift the rear gears. Undo the rear derailleur cable anchor bolt. Unthread the inner cable from the grooves and guides that are on the rear and underside of the rear derailleur.

ii Pull out the cablevisionPull the inner cable out through the derailleur'south barrel adjuster. If there's a protective cap crimped on to the end of the cable, a expert tug at this point will pull it off.

3 Remove the lever Unwrap the record from the right hand side of the bar. Roll the rubber lever hoods forrard equally shown hither and utilise a 5mm Allen key to loosen the retaining commodities which holds the brake lever to the bar.

4 Slide the lever off of the handlebar Nosotros exercise this considering it is extremely hard to thread the new inner cablevision through the shifter with it on the bar, a blueprint declining of the SRAM Hydro R brake/shifter unit. I haven't quite fully removed the former inner cable here, you tin do it earlier or after lever removal, it doesn't matter which.

five Select the nipple Near new gear inner cables have nipples on both ends. One end is a cylinder with squared off ends (the top one in this shot), the other end is a shorter cylinder with domed ends. For Shimano and SRAM shifters nosotros need the squared off end; the other fits Campagnolo shifters, because having the same fitting for such a common spare would exist too simple. Trim the other end off.

6 Cut off the 'incorrect' nippleUse the sharpest cable snips yous tin can discover. These are Park Tool CN10C Pro cutters and are the benchmark. They're ideal for trimming inner and outer cable and have shaped areas (visible below the pivot bolt at the bottom of the shot) that are great for reforming cablevision outer for a tidy stop.

7 Feed in the new cable With the fresh cable cut, you can feed the end into the hole in the lower inside edge of the plastic lever housing (see the bottom of the shot). It goes into a red plastic slice and up and around the ratchet mechanism, exiting the lever trunk through a hole in its top exterior edge. There is a slot (just visible to the right of the top piece of cable) which leads to the aqueduct into which the outer housing for the bars meets the shifter.

8 ​Pull the new cable through Make sure that when you attain the last bit of inner cable, that the nipple goes cleanly into the hole in the shifter body and sits fully into its seat. Without kinking the cablevision, give the end handing out of the shifter top, a tug just to be sure.

nine Lube the cablevision Grease the section of inner cablevision that will be  nether the bar record. There are some precipitous turns to make it from the shifter and around the showtime bend of the bar, so the grease will help mitigate the friction.

ten Replace the lever Refit the restriction lever on to the bar, ensuring it's at the right height and angle. Bolt information technology downwards with the 5mm Allen central. With the run of housing ready, thread the greased inner cable through the outer.  Push the outer ferrule fully home into its pigsty in the shifter body. Tape the gear and brake lines to the bar.

11 Thread the cable Depending on your frame you might accept external cables, in which example just thread your fresh inner cable back through the stops and housing runs to the rear derailleur. Internal routing technique volition vary past make and model. This Turner Cyclosis frame uses removable panels (the blackness oval). In this case we just need to thread the end of the inner cable into the cablevision cease and through the tiny pigsty in its base. This volition allow the inner cable to enter the down tube.

12 Route the cable through the frameRemove the bolt which retains the plastic cable guide. again frames very on how the guide is accessed, Many, like this Turner, employ a uncomplicated hole in the bottom bracket shell to allow access for a long 4mm Allen fundamental.

13 Push the inner cablevision fully into the downtube Y'all'll need to poke your fingers into the bottom bracket beat out and into the bottom of the downtube.  In that location will most likely be a stride border stopping the inner cable from just poking into the BB shell. Feel around for the cablevision finish and coax it through.

xiv Thread the new inner cable through the appropriate slot in the guide, its usually the one on the right hand side (left in this moving picture), the centre slot is for the front derailleur cable, but as this bike is a 1x set up, there is no cable. Now the tricky bit: Pull the cablevision through and as you lot do slide the guide back up the cable and piece of work it back inside the bottom subclass shell and into its normal position. As you do this you likewise need to slot the cease of the inner cable upwardly the inside of the right paw chainstay.  Secure the guide with the 4mm Allen primal. It takes patience of a saint and the fingers of a child to manage it cleanly. Worry not, even the best mechanics find this tricky.

fifteen Thread the cable through the stay The end of the inner cable is inside the chainstay. On this bike the blackness panel unscrews and you can choice the end out. Thread the blackness housing on to the cable and re-screw the housing dorsum into the chainstay. At this point we ofttimes pull the cable tight with our left hand and operate the shifter with our right, just to check the inner cable is running smoothly.

sixteen Fit the last piece of outer Thread the concluding slice of outer housing onto the inner cable and ensure that the ferrule is seated into the stop in the chainstay.

17 Fit the cablevision into the derailleur Pop the stop of the inner cable through the rear derailleur'southward barrel adjuster. This is actually quite a skill. Take care not to impairment the end of the cablevision and cause an ugly fray. If it does, you should have enough spare cable to make a trim and get once again.

eighteen Tighten the cable clench Route the cable inner through the grooves and guides of the rear derailleur into the clamp. Pull the cablevision so that it is tight, simply non and so that it pulls the derailleur's parallelogram, then tighten the clamp bolt. Y'all at present need to check the indexing of the rear derailleur.
