buckled wheel

[dannyboy]

can you straighten a wheel if so how cheers

adjusting the spokes with a spoke key can sort it if its not too bad. its a bit tricky though.

Is this the bike you just bought? I feel bad now for encouraging you

Only joking, you should be able to fix it as long as the rim isn't actually damaged, tricky though as mentioned above.

Have a read of the many wheel truing webpages, such as these:
http://www.kenkifer.com/bikepages/skills/spokes.htm
http://www.parktool.com/repair/readhowto.asp?id=81

I've only fixed mountainbike wheels myself, though I imagine it's much the same for BMX.
Go slowly, remembering how much you've tightened/loosened the spokes.
A bike shop will also do it, charge will depend on the time required - might be cheaper than you think, worth asking if you're worried about damaging them.

was it the wheel with the db bars
as you will need to despoke it
then straighten the rim with pressure then respoke it

 as obi wan space cadet just said , tricky but possible if the buckle isn't too bad.on the other hand  if it is got a ding, flat spot or is egg shaped then it is time for a new wheel rim.

ive fixed wheels with flat spots and very bad eggs
prob is they only good for show as it weakens em lol

Have a read of that for tips.
