How can I add full fenders to a frame with no braze-ons?

Question

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?

Answer 1

Crud Roadracer Mk2s offer a bit more coverage than raceblades I believe

Answer 2

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.

You can use cable clamps to attach to the fork arms and seat stays for the fender stays. If the bike has bosses for center-pivot brakes you can anchor the top of the fender to them. Without the brake bosses, though, I'm not sure how you'd anchor at the top.
