Designed to be a proper BB for installing Praxis LYFT MTB crank, 30/30mm. And also RACE FACE CINCH or Rotor REX MTB and more cranks into 73MM BB30/PF30 mountain frames. Our patent pending design keeps the Enduro 6806 cartridge bearings outboard of the frame 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.
