Mechanic meisters.....
I had a new group installed and rode for months with no problems. Now on a couple rides recently (but not consistently) my chain is dropping on the shift from big to small chainring.
I have taken a look at the biggest cog on the cassette / small chainring setting and the chain is very close to the inside of the front derailleur. IE this looks ok, at least to my untrained eye, and I don't think is the cause of the problem (plus I can put the back wheel on a stand and shift a hundred times from big to small with no drop).
The drops have happened I think with the chain on the 3rd or 4th biggest cog on the cassette, so I don't think the angle of the chain is a cause either. btw, I'm running Campy 11 with 34/50 crank and 11-25 cassette.
I'm an awful mechanic when it comes to fine-tuning like this, plus i just moved and only have basic tools. If I can find a K-Edge Chain Catcher around town I'll get one....but even though I get piece of mind this will still not solve the problem.
Any ideas? I've thought somehow maybe pedal torque or cable tension - the drops seem to happen when I've started a climb in the big ring and shift down to continue. But it's not like this is any new behavior, so why now?
Grateful for any thoughts, thanks...
