im pretty sure the redline recon is a mid bb. which a usa would NOT fit. its only like 20 bucks for a mid bb. and then you have to get the right spindle size. which is probably a 19mm.
its nothing much just showing you. u prolly hate it. but it worked pretty good for me.
the only downside to this is that u have to run a little bit smaller wheel because of the spring. it also looks pretty dumb.
