Reasonable suggestion, though when I can I prefer to do my research before wandering into a store. That way I get the opportunity to shop around a bit first, or order the part through my preferred LBS (who otherwise don't have a lot to do with BMX), rather than feeling pressured into buying from the first place that has a matching part.

Still hunting around online myself for information about these, but if anyone recognise them or can at least point me in the right direction please sing out.
