Mudguards on a Carbon CX

simonj

Hi, has anyone successfully managed to fit full coverage mudguards to a Canondale SuperX or other Carbon CX whilst it has 35mm CX tyres on? Thanks

More info, the bike has no mounts front or rear, it has a hole in the top middle of the fork, but no holes on the rear bridge by seat or by crank. If anyone has managed to fit any which ones will fit and will they go straight on or do they need a bit of tinkering? I have some Crud Roadracer, but I don't think they are wide enough and also I have no brakes for them to fit to. I also have some SKS Chromoplastics, but again no appropriate mountings on frame or brakes. I have looked online at long raceblades, but think they need brakes mounts?!?!

I run a set of SKS 32mm Raceblades. It has an outer diameter of 36mm so there probably won't be enough coverage for 35mm tyres.

They strap onto the fork legs and seat stays, no brake mounts needed.

For the SKS Chromoplastic mudguards, I can think of several ways to attach them:

1. At the QR wheel axles if the mudguard metal stays are long enough to reach. You will need extra long QR skewers and some serrated washers to prevent the mudguard stays from damaging the dropouts when they are clamped into place.

2. Fabricate some eyelet brackets that attach to the rear seat stays and fork legs. These are nothing more than strips of metal with nuts and bolts holding them together like band-on front deailleurs. The strips of metal can be cut out from a biscuit tin (needs to be atleast 15mm wide, two layers thick). Then tape down a layer of old inner tube for surface protection before banding on top of it.

3. Since there is no seat stay bridge attachment point, add a brake booster and attach the mudguard plate to that instead. You could even make one out of a thick wired coathanger.

4. Since there is no chainstay bridge attachment point, fabricate one by bolting on a strip of metal using the same bolt that holds the bottom bracket cable guide on (you could even drill and tap another hole into the bb shell if needed).

I put a set of SKS chromoplastics on my Colnago CX which has no mudguard fixings at all.

I just used p-clips and zip ties, worked fine and the guards are quite secure.

You need some P-clips to fit around the fork legs and seat stays:

Cheers guys. Was looking at the p-clips, rears look easy, but the front forks are quite chunky, so wasn't sure if they'd fit!?!? Also how did you do the zip ties bc , I'm worried about the metal fasteners rubbing against the frame if zip tied.

You can get all sizes of p-clips (try ebay) - I think I had to use 26mm on the fork legs!

Protect your frame with old strips of inner tube if anything looks like it might rub.

In the days of steel forks, I was happy to cable-tie the mudguard stays directly to the bottom of the fork leg, I wouldn't do it with a carbon one without some form of protection as the fretting would simply wear big chunks away
