I replaced my chain yesterday, a shimano DA 9 speed. This is the first time i have changed a chain myself.
everything appeared to go well - i counted the links on the old chain, made sure the new chain was the same number, and it went on fine.
i just tried to ride on my trainer and the chain was jumping. I had the impression that maybe the chain was too long - it seemd to skip every few rotations of the cassette....therefore i shortened the chain by first one link (still jumped) and then 2 links shorter, and the jumping remained. The "jumping" seems to occur where the chain enters the derailleur, causing the derailleur to kick forward and then back quickly, and the chain seems to skip over the cassette.
right now i am wondering what the problem is - specifically maybe the chain was in fact originally too short, and now i have only made the problem worse. but then common sense tells me it is probably too long, but i counted the links so carefully.
does anyone have any ideas what might have gone wrong?
