This is driving me mad....Cruds

[PeteT]

Hello all - first post here (after the intro. one) so please be gentle with me!

I've got a Scott Speedster S30 (2011). It's got mudguard eyes at the back, but not at the front. Clearances are tight but I can get a 5mm Allen key under the brakes at both ends, so have fitted a set of Crud Roadracer Mark 2's as I'm doing an Audax which requires guards.

I've followed all the instructions, watched all the tutorials on the Crud site (including the tricks and tips) and adjusted as necessary, but the damn things STILL sound as if they are catching on something. Looking closely with a torch, there seems to be enough clearance; the little brushes that skim the rims aren't causing the noise - I just can't trace it. The wheels seem to spin OK, but the catching noise continues - it's very frustrating and annoying when riding, and also disconcerting. I wondered if it was the small rubber pips on my new tyres causing the problem, but I'm not sure it is.

Do they sometimes just settle down on their own? They are the only realistic option for the bike that will give some decent protection. Should've bought the S35 Scott really (a limited UK model with extra clearance for guards), but not quick enough - they'd all gone when I was ready to buy.

Thanks.

Is it the front one or the rear one?

I found that the front piece of my front Crud Roadracer rubbed but a little piece of packing under it lifted it enough to sort that out.

If it is the rear one, make sure the side of the guard next to the front mech. isn't twisted over.

Even if you sort the noise out in the dry, you will get some rubbing in wet conditions when grit sticks to wet tyres. Ride through shallow puddles to wash it off/out. Clean under the guards with blasts from a hose or garden spray to avoid silt build-up on consecutive rides.

Hello Pete. I have an S 30 2009 model with no eyelets front or back. ditto what Colin J says a few layers of electric tape under the front bit of the join between the main bit of thje front mudguard and the nose piece was needed to lift the front of the nose piece a bit.

Also ditto what he says about washing the crud out of them. With tight clearances you need to. One good thing if you break any part Crud will replace for nothing if you send the correct postage stamps to them. More details on crud website.

Not many Audax organisers still demand mud guards .

On some frames you might find that you need to stick a bit of rubber or similar to the area that is cable tied to the brake due to the way the arch is angled, this means the mudguard isn't being deflected down to steeply & thus making contact with the tyre.

Are there any injection moulding bits sticking off the tyre? I've had a problem with those clipping mudguards before.

what he said

couple of minutes with a sharp knive shaved em off and silence the bike.

Most folk seem to love their MK2 Cruds, but I never could get Mk2's to fit right on the rear.

Mk1's have always been fine on every bike I've fitted them too though, go figure

Thank you for all your feedback. The noises were coming from front and back guards. The back has now settled after some fiddling - runs as sweet as a nut, with no evidence of interference from the guard. The front however.....well, I've tried the tips given on here (packing out etc) to no avail. I even removed the nose of the guard - that made no difference. I've removed all moulding pips off the tyre. Still the 'catching' noise persists.
Problem is, I can't pin it down to an exact location. I'm beginning to wonder if the wheel is out of true (although it shouldn't be on a brand new bike that's done about 80 miles, no potholes involved).

I'll just ride with it for a while longer and see if it settles. My biggest worry is that something will wear through the tyre & it'll go 'pop'! If I can't sort it, then I'll keep the back one on and look for an alternative solution for the front - unfortunately whilst most Audax organisers don't require mudguards these days, the Dartmoor Devil does - and I'll be riding that, so have no alternative but to find a solution.

Cheers all.

For the sake of sanity take of the mudguard and see if the noise is still there. There is a possibility the brakes are catching on the rim(s)

Now that would be embarassing

I struggled to get them to fit on my Secteur yet I know others who have managed it, I probably lack the patience for all the minute fiddling and tweaking needed after using the very easy to fit Raceblades.
