buckled wheel

Just arrived at work and noticed that my wheel was starting to wobble on the last stretch of my 10 mile commute.
When i say wobble, there is no visable side-to-side movement in the wheel like a normal buckle.
It seems like there could be damage in the hub, or the wheel has gone slightly oval!
Can anyone give me any clues as to what to look for to solve my wobbly wheel dilemer!
I'll go and give it a better examination at lunch time.
Cheers

you can true a wheel, you need a spoke key. it'd be easier to do it a jig but it's possible on the bike. basically, the 'nipple' where the spoke passes through the rim is a nut and that end of the spoke is threaded (ie it's a bolt). you will note that the other ends are, alternately, joined to each end of the hub. if you tighten a nipple, the rim will move towards the end of the hub its attached to. confused? actually doing it will be just as confusing - you HAVE to do it and learn from trial and error, or get a wheel-trueing/building lesson.
a wheel can be trued for roundness too, so maybe you've lost 3 or 4 adjacent spokes (which would be unusual), or it could be a hub problem as you suspect. are the cones tightened up without a wobble still? it could be a break or dink in the rim - only you (or your local bike shop) will be able to tell from looking at the whole bike0 -
If you lift the back wheel off the ground and push the wheel from side to side you should be able to see/feel any play in the hub. This would mean (as Ross said) that the bearings were shot or need adjustment.
If there's no play in the hub, when you spin the wheel and look down the line of the rim (from the back of the bike, which is easier if someone holds the wheel off the ground for you and spins it), you will see sideways wobble.
If you look at the wheel side on when you spin it you should see if it is "out of round".
If you have a go truing the wheel yourself I would recommend the Park tools website:

This is the page for truing wheels and is long winded, but worth the read to avoid what can be quite a frustrating, but ultimately very satisfying job.0 -
My wobbly wheel ended being my tyre!
It had started to bulge from one side where the rim touches the tyre, infact the whole rim area of the tyre had delaminated badly.
It's a Continental Sport Contact 26" x 1" and it's only about 6 weeks old, the front one seems ok. Maybe it just can't handle my 18stone!
Better take it back to my lbs to see if I can get a refund!

I think Conti Sports Contact are too flimsy (and they are puncture prone), the rubber seems to be too soft. Go with Specialized or Schwalbe for reliable commuting tyres.Stuww wrote:My wobbly wheel ended being my tyre!

Yep, just ordered some Schwalbe Marathon Plus 26 x 1.35's, hopefully a better tyre!

A MUCH better tyre IMHO - albeit not completely slick, but you shouldn't notice any effect on performance (and for all the puncture delays you don't get it will make you much faster!)0
