I recently picked up a bike I want to ride in Seattle rain, but missed the fact that the frame had no braze-ons for attaching full-coverage fenders. I already have a set of SKS Raceblades, but they only provide partial coverage. Do any manufacturers make full-coverage fenders I could use?
Crud Roadracer Mk2s offer a bit more coverage than raceblades I believe
I have suspension fork with absolutely no brazeon or eyelets. I have SKS Chromoplastics which I used to attach the normal way to my previous steel fork, which had the eyelets.
These Chromoplastics, if not perfect, have served me very well for some years now (with a lot of off-road abuse).
These fenders are currently being manufactured in an "upgraded" version called Longboard:
I solvd the problem very satisfactorily by passing a ziptie through the safety-clip bolt hole (lower-left part of the image below), and then clamping the metal shafts (which had to be shortened) to the safety-clip, the way they are supposed to be.
I put a patch of used-tube rubber between the safety-clip and the suspension, to avoid paint damage and to improve firmness and dampening eventual noise and vibration.
My suggestion would be to get some aftermarket safety-clips and do the same on the rear part of the bike. And if it is not possible, rubber, zipties and drilled aluminum plates solve a lot of problems.
The safety clip I refer to is this:
If your bike has classic-style steel rear dropouts, you might try the Rodriguez Components Universal Fenderizing Object. It's basically a machined screw and plate set that gives you a secure fender mounting position. Plus, hand-made in Seattle.
Otherwise, zip-ties or hose clamps can mount the fender stays to the seatstay and fender brackets to bridge the brakes can be improvised out of pieces of flat stock.
