10 spd levers work with 9 speed derailleur
I have a full group of DA 9 spd but I can't get my lever to let the cable go so it shifts down to the little ring. I spray the whole can of WD40 this afternoon. If I have to get a set of shifters, they will be 10 speed shifters. Will it work with the 9 spd derailleur along with the 9 spd cassette? How about 10 spd cassette?
