im after a cheapy front bmx wheel with 14mm axle to build a bc wheel as mine seems to be broke , will not need tire or tube 
ive got one, the bearing are bust so it wobbles on its axle, but i never really found it a problem for BC.
On a bmx=CRAP
on a BC=functional
its a good strong wheel though, 48 spoke diamondback
i see about getting mine fixed , but ill get back to you simon 
Brand new direct from retailer
When I was building my BC wheel about a month back, this was the cheapest brand new 20" wheel with 14mm axle I could find including postage.
