This Ribble Cycles came in with a faulty front shifter, so we agreed to replace the gear cables (front and rear), but having measured the chain, also replace the chain and cassette with Shimano-Road goodies. Internal cable routing looks great, but can be a real pain when it comes to cable replacement. Ribble Cycles have done a good job on this, although getting the cables through at the bottom bracket was uber tight. Thankfully, the Park Tool IR 2.1 kit made this a damn sight easier.
