Asking a question of the experts here -
I'm doing the next door neighbour a favour and servicing the wife's commuter bike and the drivechain has had it.
Everything bar the shifters and mech are fubared. Unfortunately it's a 5 arm chainset and they're in short supply, or so it seems. It appears the cheapest option (this is just a keep it running type thing we're doing) is to buy another chainset
Something like THIS but it does seem to be a 9 speed according to the FSA website.
The question is then; how will it work if I keep everything else 8 speed?
Your experiences would be appreciated
