Crud road racers and carbon frames

amaferanga

I remember reading a post on here a while back where someone was saying their Cruds were eating away at their frame under the fork crown / brake bridge. Yesterday while giving my bike a good clean I noticed that I have the same problem even though I've probably done no more than a couple of hundred miles with them on. They're off now anyway, but they won't be going back on unless I can be sure that they won't eat away at the frame. I was thinking about a strip of rubber between the 'guard and frame, but not sure it'll help much.

Do others have the same issue and if so how have you dealt with it other than just not using them? I wonder if Mr. Crud might have anything to say about this issue?

A piece of tape under the fork crown should be more than adequate.

Maybe, but I'd be replacing the tape regularly if the amount of wear in just 200 miles is anything to go by. Might try some frame protector stuff I have lying around.

My last C G replacements included rubber circular guards for under the brakes but I dare say could be used elsewhere, so it seems that the makers are one step beyond, sorry ahead. :oops:

fed up with mine as bits seem to snap off, just by looking at them.

So took them off last week & exceptionally upset with the amount of wear marks (bike shop fitted them)

I brought this up in a post in November I think, just as the Cruds were coming out.

The guards ate away the forks and rear stay or my carbon Bianchi. They even ate away the ultegra brake calpers after a couple of hundred miles.

I removed them and informed Pete Tompkins at Crud. He said he would arrange for the next batch of the instructions to include taping under the fork bridge.

I did think there would be a few posts once the guards were removed for the summer!

It's not just the Cruds, but it's a similar problem with Raceblades too - grit gets under the mounts and the vibrations cause fretting and erosion of the paintwork. Frame protection tape over the mounting points should see you through the winter

I used electrical tape to wrap around my carbon forks and seat stays, and also stuck some under the fork crown and seat stay crown - have had no problems. Most people I have seen with Cruds on don't seem to have put anything underneath to stop the wear.

Someone I know had to junk a frame because they ate through his carbon fibre seatstays.

Dunno - I use RaceBlades (have had them on for 3 or 4 years, before Cruds came out) and I've got about 3 layers of thick tape (Duck Tape brand helicopter tape stuff) on the fork and stays where they clamp on.
I've even seen someone with bits of old innertube protecting the frame.
