How To Install Shifter Cables Road Bike

There'southward not a pro rider or mechanic in the world who wouldn't swap a meridian-of-the-line groupset connected up with grotty, sometime cables for an entry-level equivalent with fresh, snappy ones. Constant utilise and exposure to the elements means that the lines joining shifters and derailleurs will eventually deteriorate and start to affect your shifting performance – the most mutual symptom being a reluctance to shift downwards, every bit your derailleur springs start to lose the battle against increased friction.

While a quick eject of lubricant tin often freshen them up, once they start to experience gritty it'due south time to bandy both inner and outer parts.

Although internally routed cables can evidence tricky to supersede, if your lines run aslope the frame, swapping them isn't a catchy chore. Merely make sure you have the right tools, then follow our 8-step guide and get stuck in.

How to replace road bike shifter cables

Step 1: Prep the bicycle and cut the onetime cables

Shift onto the smallest sprocket or chainring. Using cablevision cutters, chop the end caps off the cables. Undo the anchor bolts on your derailleurs.

The front end sections of outer cable run under the bartape, so y'all'll demand unwrap this to get at them. Roll the restriction hood forward and carefully unwind until just beneath the levers. Cut the electrical record holding the outer cabling in place.

Pace 2:Strip the outer and eject the inner

Now disconnect the outer housing from the frame stops and remove information technology. Next remove the inner from the shifter. Gear cables commonly thread in from the side. Push the cable backwards towards the lever.

The shifter will demand to exist selecting the highest gear and the lever pulled dorsum to the bar for the cable to be released.

Step three: Measure upwards and cutting

Cut your new cable outers to match the length of the ones y'all just removed. You lot'll need to utilize dedicated cutters to become a make clean finish – it'southward important to go the ends every bit flat as possible.

Once cutting, if the liner inside the cable seems to be closed off, use a pointed instrument like a pick to open information technology out again. Push the ferrules onto the ends of the cables.

Still in the highest gear, fit the new gear cable past sliding it gently into the lever at the aforementioned bespeak that the old cable exited. The end should popular out the other side, although it may require a little wiggling.

Step 5:Slide the outer cabling into place

Slide the outer cable over the inner wire. Thread the wire through the frame stops and slot the ferrules on the outer section into place. Tape the first department to the bars.

You'll demand to slide the cablevision through the guide under the bottom bracket. That's it for the front but the rear volition need the last section fitting between the final cease and the rear derailleur.

Step 6: Attach to the derailleur and tension

Pull the cable tight and attach to the derailleur. Now, without pedalling, shift the lever several times as if to alter into a bigger sprocket or chainring.

This will put tension on the cable and assistance it settle into identify, meaning your gears are less likely to leave of adjustment subsequently. The process is the same for both front and rear derailleurs.

Stride seven:Dial information technology all in

Ensure the barrel adjuster is dialed in. Undo the cables at the derailleur and pull them taut once more to remove any slack that's developed before refixing.
