Hi all, I've encountered a problem which is confusing me somewhat. I've just changed my chainset from a standard double to a compact double, as I'm off cycle touring soon and wanted some lower gearing for when the bike is loaded. The new chainset altered the chain line by sticking out from the BB a little more - I've adjusted the front derailleur to accomodate for this, and it all seemed to work and shift fine with high and low limits dialed in. I've also removed two links from the chain to take up the slack created. However, for some reason the right hand shifter for the RD started to jam, so I played around by trying the original chain length and the shortened one, and with some undoing the RD cable and playing around with it I managed to get the shifter working again. This then did it again 10 minutes later whilst trying to shift into one of the top cogs, after some playing again I got it working again. I immediately took the bike for a spin around the block but then the left hand shifter also then jammed. It was not the chain catching on anything as I could still pedal within that gear, I just was unable to change. I've never experienced either jamming in the 5 months I've had the bike, and then they both do it straight after installing a new chainset. The strange thing is that with a gear cable undone and slackened off they still don't shift either way, making it feel like it's the shifters where the problem is, but then after some playing they start working again and I do the cable up again. I was wondering if it's the cables as I bought the bike second hand and have kept the same cables, however I wasn't experiencing any shifting problems before the chainset change and they seem in good condition - plus I really can't afford a new campag cable set to find out that wasn't the problem right now. Does anyone have any ideas that I may have missed before I go on a desperate hunt to find a bike shop that will repair my 90s Campag ergo shifters within a week and a bit?
