Time VXR frame (super groovy - couldn't be happier with it), Shimano Octalink BB and FSA team issue crankset, 10 speed Campag Record set-up.
Chain has been jumping intermittently on the last 2/3 sprokets, when I'm pushing out of the saddle. Nearly killed myself in a race on Sunday :eek: Have adjusted (in line with Campag literature, etc), till I'm blue in the face but to no avail. This is driving me fcukin' crazy!!!
2 things jump out at me - 1. Chain line is really poor on 53 x 23 (biggest sproket), not that I'd ever use it unless I fluffed a shift. 2. Last 4 sprockets are titanium on record block and seem to have worn quite a bit over the last year's racing. So I'm thinkin' either some compatibility problem between the bb/chainset and Campag cassette combo, or just plain old wear on the titanium sprockets. Anyone had any similar experiences, or got any ideas 😕
It's probably wear rather than compatability. Ti sprockets wear more quickly than steel, and a season of racing is probably the most you can expect from them. A quick check to see if this is the case is to borrow a wheel that has a newer cassette and see if it has the same problem.
