Hello,
I bought a new crankset which I thought was a close match to my old one,
new one is 26-??-48 old one is 28-??-48, but now can't seem to get the
front derailleur aligned right. If I move the derailleur up the seat
post the chain scrapes on the bottom of the derailleur, if I move it
down it doesn't clear the big chainring.
Does the extra two teeth really make such a difference that I'm going to
need to invest in a new front derailleur or larger chainring? Or could I
have another problem, like too much slack in the chain perhaps?
Thanks for any help,
Ian
