Got a set of these
and I'm trying to fit them to a Trek frame/fork which has mudguard eyelets.
I've only worked on the front guard so far, thinking it would be the easier of the two, and have spent 4 hours swearing in the back room over the last 2 days. I can't work out how to attach the guard to the fork crown. I have 105 brakes and on the back of the crown is what looks to be a threaded hole to which the brake is attached at the front. None of the bolts supplied with the kit (m4 I think) are big enough for this hole and I got the next size up today and they're too big.
Regrettably I can't return the things as I've cut the stays to length (thinking that would be harder than bolting the thing to the frame!)
Apologies for unashamed road content!
