wheel clicking

Robbie1958

I have ridden over 100 miles in the last few days on my Colnago road bike, and it seems to have developed a rather annoying clicking sound from the front wheel. I have removed and re-fitted the wheel and have also taken off my computor, but it has not cured it. i wondered if it is possible for the bearings to become dislodged inside the hub, or perhaps there is another reson. I have checked the spokes and they don't appear to be loose, broken or bent, and the wheel runs true and is not buckled. The brake pads are clear of the wheel also.

The wheels are Mavic open pro's with continetal 700 x 23c tyres. i clean the bike whenever i get back and there is nothing sticking out of the tyres that might cause a sound.

Have you checked the threaded knurled nut holding the valve through the wheel rim is tight.

Sometimes makes a clicking noise when its loose

Hi Richard

There is no nut holding the valve in place on either wheel.

Does it tend to happen at low speed or is it there at high speed too? the only reason I ask is i just did london to paris with a guy who had a low speed click and it was a stray spoke nipple inside the rim. seemed to go away after 8mph (centrifugal force and all that)

No it happens from the off. and is loud enough to be annoying. Thats why i wondered about maybe ball bearings

mmm, maybe you have dead posh wheels and tubes :shock:

I thought all tubes come with them

Do you have a wireless computer with a magent on the spokes and receiver on the front fork? If so - are they by any chance hiting each other each time the wheel rotates?

I had a clicking coming from the drive train.

Wheelrim was cracked in about 6 places!

took my computor off so it isn't that. also if i lift the bike and spin the wheel it doesn't make the clicking noise, it's only when i sit on it and pedal, so obviously under pressure.

Sometimes if the inner tube valve stem isn't in straight, or particularly with deep-rim wheels, as the tyre is compressed and deflects on each revolution, the valve moves slightly and touches the rim. When the wheel spins when elevated, there is no pressure on the tyre. Try removing the inner tube and wrapping some electrical tape around the valve stem - worked for me on some Ksyriums.
