Hej Sten,
It is good to hear I am not the only one. I'll have to check if there is
a tolerance on the BB, although that doesn't worry me. Tolerance doesn't
matter for the riding experience.
Tacking the shell seems a little crude. I'll try clamping it down using
a bolt and large washer, having the washer pushing on the shell, keeping
it im place. Something like that anyway
regards, Dirk
