Having a maddening problem. My chain skips under load, but only on the 11-tooth cog.
I get the skips on the big gear in front, so its clearly not overlong chain.I've tried almost everything, new chain, new cassette adjust limits & indexing both deraileurs & b-screw. (crankset & FD are also new).
However, I am running a jank setup: (11spd) Campy shifters/deraileurs, Shimano cassette (11-28 ultegra), universal chain (wipperman) & chinese powermeter crankset (shimano hollowtech2 style, w/ Ultegra chainrings). This crankset has a limitation that it adds +2.5mm outboard chainline (wider Qfactor).
11speed is fully compatible across companies in my experience and based on online information.
So what is going on with my damn 11speed cog, why is it the only one skipping? I am going insane
Possible answers I've come up with
1) Defective cassette? 2) Weird compatibility issue only affects 11tooth? 3) Is my frame broken and I don't notice? 4) wider chainline should make it better not worse? 5) is the FD veeery slightly rubbing and somehow that drops the chain on the rear?
