Chain replacement time has arrived and this will be the first time I will have done it myself. Slightly falling at the first hurdle in that I'm not really sure what length chain to order.....my gearing is a 52 / 36 chainset and an 11-28 cassette. The options are 114, 116 or 118 links.
Can I simply compare the new chain with the chain that's coming off? My understanding is that chain stretch is a wearing of the links, not a physical "stretching" of the chain, so the old chain should be the same length now as when it was new, right?
Novice questions I know, but if somebody would point me in the right direction I'd appreciate it.
