I am waiting on some sks p35 fenders for my cross bike (canti brakes). I think the hole in the fork crown should work but I have a carbon fork with no eyelets in the front. Do you guys think a ziptie or p-clamp will be ok with a carbon fork? I know it is not recommended to hang racks on the side of carbon because of structural weakness... it seems the best solution would be a piece of metal that could fit around the axle between the fork and the quickrelease clamp to simulate an eyelet. If the QR is clamped on tight enough it should be pretty secure. I dont know how to construct something like that though.
