I popped into a bike shop today to pick up a replacement for a snaped gear cable.
I was told that my chain is probably getting on, and when changing a chain, you should also change the rear cassette.
Now, this is for a commuter, which is a MTB with (not quite) slick tyres. Given I never go off road, having a 11-34 on the back is not really necessary, especially with the triple on the front, it should given me plenty of range.
The question is, can I replace my 11-34 with a road bike style 11-25? Are they compatible? So many questions. If only I thought to ask before leaving the shop...
