I've just had to change my chain and cassette. I had 12-27 but, it being a year or two after getting that and the hills having grown
, I've opted for 11-32.
I have a nasty feeling I need to go for the Rival long cage rear mech.
Is this right ? It certainly won't go on the mid cage I use on the 12-27
Anywhere cheaper than £69.99 ?
Is this the mid/long cage too ? <hopes so ...>
