Drivetrain Problem With Veloce
Hi,
Have recently been having an issue with my 2012 Veloce 10sp. The shifting etc has been perfect for 14 months and no tweaking or adjustment required.
About 2 weeks ago I was cleaning the drive train out and knocked the chain off at the cranks. No big deal I thought, finished cleaning and replaced chain but I immediately noticed I could no longer change to an easier gear on the cassette by as many gears at once as I used to. As in, I could change down 3 or 4 previously in one go but the shift lever now seemed too "tight" and would only shift one or two gears at a time.
Bike still seemed to work OK so I thought it might loosen off while riding however no my chain is regularly (almost continuously) skipping on gears under power but not when I turn the pedals while off the bike. The shifting is more sluggish and ponderous than it was going both up and down the cassette.
I have tried taking the slack out of the RD cable using both the barrel adjust and pulling the cabe through the set screw but this made no difference. Think the limit screws are fine as I can shift to all gears successfully without leaving cassette at either end or shifting gears on its own. Checked for wear on the cassette and it looks OK. Checked the chain (visually) for stiff links but couldn't see any.
Any other ideas? Apologies for the lengthy post.
I also posted this in commuting workshop so sorry for the double post.

Maybe the cable outer casing has popped out and is resting on the edge of a ferrule somewhere along its length between lever and rear mech. It certainly sounds as if rear indexing is out.0

Breaking cable, split housing, lever moved down on the handlebars?0 -
Thanks for the replies guys.
Tried indexing the rear and the shifting seems fine, also looked at the integrity of the cable along it's length and it seemed OK although after over a year its maybe due replacement anyway? However when riding to work this morning the chain was still skipping on gears particularly in the middle of the cassette. Will take it to LBS on the way home.

Have you bent any of the chain links when you shipped the chain?0

Thanks for the further replies.
Apparently the cable had partially siezed but the main offender was a heavily worn chain (I don't have a chain tool to remove and check this ATM) and a partially worn casette.0 -
You don't need to remove the chain to check for wear. Get a chain checking tool and use it frequently, or alternately use a ruler held against a taut chain. Replacing the chain at 0.75% wear should mean you get through at least 3 chains before you need to consider replacing the cassette.0
