Total speculative brainstorming here: I installed one of the regular mini racks on my clem earlier this year, using a sheldon nut on the back of the crown so that i could space and elevate a fender mount tab as high as possible, but also so that there was no slop/wiggle between the mounting hole and stud diameters. Interestingly, I had to use a thin washer on the front of the crown because there weren't >quite< enough threads on the top strut of the rack. Otherwise it "looked" like it was tightened all the way in at a glance, but the nut was actually bottoming against the last of the threads. A total dimensional coincidence. I could imagine that stud/strut becoming fatigued if left to move and vibrate, and a rider might never know it was an issue because it wouldn't ever loosen up.
That said, i somehow interpreted that the problem was with the ones that mount to the canti studs. No matter what, this is an issue of a user's responsibility to exercise good judgement, and it bothers me to no end that there have been lawsuits over it. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
