Just doing some fettling on the mountain bikes and noticed the lower jockey is trashed. I have a couple of spare roadie jockey wheels and can't see any difference with those on the full bouncer, is there any reason not to use these spares? Nothing flash on the bouncer, LX deore rear mech.
In reply to Horse: upper and lower are different, 8-9 speed are different. Bushes are different and the length of the securing bolt is different are all problems you may encounter. They all have the same materials however.
