Praxis Works BB30/ PF30 Converter Shimano 24mm Road Bike Bottom Bracket 68mm BB

Description

Designed to be a proper BB for installing Shimano™ Hollowtech II steel spindle cranks in either BB30, PF30, or Specialized’s OSBB frames. Our patent pending design keeps the cartridge bearings outboard of the frame right on Shimano™ spec for greater rigidity and free of frame/c-clip tolerance issues that other systems deal with.
Simply press in the longer non-drive-cup, then the shorter drive cup threads into it. As the drive cup threads in, our trademark Collet system expands to a precise limit evenly dispersing pressure for a super tight fit. With both cups connected and our collet set exactly to spec, there is no chance the bearings can come out of alignment or wiggle/walk out of the frame. This design also uses a compressible o-ring on the
non-drive side
cup to compensate for frame shell width discrepancies.
New updated design with Rubber expanding collet.
This version for Shimano™ Hollowtech II steel spindle road cranks only.
Designed precisely to Shimano bearing stance & chain line spec.
Forged & machined heat-treated 7075 T6 Aluminum
For 68MM BB30/PF30 and older Specialized OSBB Road frames
Not
for BBRight, BB386EVO, BB30A, BB86, BB92 frames
68mm version cannot be used for MTB Cranks
