On my ride yesterday in pouring rain we were coming up on a stop sign and I downshifted ... I was in the big ring and didn't realize I was getting crosschained. This made the chain drop off the big ring and it dropped all the way off to the inside. I've had this happen a couple of times before ... no biggie just push the fd back up and it gets back on (TruVatuv Rolleur/campy veloce fd) But this time I guess it pulled the chain off the cassette and into the spokes too. I heard the non normal grinding and got on the brakes just before the rear wheel locked up. Skidded/fishtailed to a stop keeping everything upright. Chain was wrapped pretty tight around spokes, I was able to free it back up with some effort and ride back home. Noticed my up shifts were slightly off. (campy centaur rd)
Got home and checked it out ... scratches on a few spokes/ one spoke definate bend where is goes in the hub (Campy Zonda's) No noticable rd damage, some scratches on a few chain links but no binding.
I've done spoke replacements before, but do you think I should take it in and have rd alignment checked too? I would think all the limit screws are set OK as drivetrain has 3500 on it. Only time I get the chain drop issue is getting crosschained with some load on it? Suggestions?
