Seems reading a bit about that BB here:

That although it is a 19mm the bearings are actually 20mm, so you should be good to go buying the 20mm 6804 2RS from eBay :)

Post by: Jon The Bassist on January 08, 2013, 11:48 AM: Most bearings on ebay like 6804rs and 6904rs are actually 20mm which is too big for a 19mm axle. You might need to shop around for the proper ones.
Having said that I know sweet FA about MTB stuff, so if it's different to BMX kit just ignore me :uglystupid2:

They will sort you out with the right ones.

Might be a couple of quid more, but easier than sending back and arguing the toss over postage etc.
