after many, many years of resisting the urge to upgrade my transmission i've now given in and will be taking the plunge to 10 speed...
my current set up is a 2x8 which runs perfectly and consists of:
8 sp shifters
8 sp chain
9sp front and rear mech
9 sp cranks and chainrings
i know i'll need a new shifter, cassette, rear mech and chain...to save a bit of cash/weight i'll be going to a 1x10 setup but my question is this:
will a 10 speed chain work on a 9 speed front chainring or will i need to change this to a 10 speed also?
any advice on this from the STW massive will be gratefully appreciated
