I have a hybrid-style bike with Shimano parts and I'd like to replace the gear cable "adjuster barrel" (?) on the shifter next to my front left brake, as I have mangled it by twisting it with a pair of pliers.
However, I'm not sure exactly what part I need to buy. This looks similar: http://www.halfords.com/cycling/parts/gears-drivetrain-cables/shimano-rd-7700-cable-adjuster-bolt-unit#tab3 ...but it says that it's for the rear derailleur rather than a front shifter, so I'm not sure if it's the right part. If not, could anyone tell me exactly which part I'd need to buy?
