Hi - new seatpost clamp (Ritchey WCS) slips when both bolts torqued to
spec (16 N-m) and even a little beyond. This is on a 'cross bike and
the clamp slides back tilting the saddle up with the normal jostling
of an hour training or a 45 minute race. Aside from the obvious (crank
the hell out of the bolts and hope they don't snap altogether) is
there anything I can apply to the undersurface of the clamp to help
this ? It's an aluminum post; I specifically avoided carbon to keep
low-tech and avoid problems like this.
Thanks........Lou D'Amelio
I'm guessing you when the bolt which attachs the saddle to the seatpost?
Replace the bolts with high tensile (12.9 grade) M8 bolts and torque it
up, it you're worried about the hut stripping replace it too, or if it's
got a special shape drill it out and put in a good quality nuts.
Cheers
Joel
