Bottom Bracket PF30?
I purchased a Raleigh RXS frame and I'm really confused. The bike says it's a PF30 BB but the eccentric BB that came with it is threaded. Also the complete built bike has a gates crankset which I think is only a GXP crank. So is what I have here a GXP eccentric bottom bracket?

Im not the seller so I have no idea about your transaction ..
Use an External bearing crank instead.. screw them external bearing assemblies In ..
Planning to use a Gates belt ? You need a Tight Belt. thats why the eccentric gets used.

Looks like possibly a PF 30 shell on the frame, with an eccentric insert that fits in there, with the eccentric insert taking a threaded 68mm English threaded bb. Maybe.

IMO, pretty close.
looking at the Rsx i have found info on.... it comes with a Gates belt drive, meaning, among other things, one of the seat stays can be split to allow the belt to be removed, and the PF30 BB shell comes with a proprietary, probably Gates, Eccentric BB, threaded for a Gates external bearings and matching crank. their most recent offering is now called Centertrack something or other.
if i couldn't do any research, and had to guess, i would just try a couple of Shimano threaded BB bearings and a modern two piece Shimano Hollowtech crank on there. if that didn't work, i'd toss the EBB and assuming you want to run a SS or Fixed gear drivetrain, i'd just buy the Beer Components PF30 BB and a modern Shimano hollowtech crank.
