THIS IS NOT AN “ADAPTOR”

Our new patented elastomer collet design keeps the cartridge bearings outboard of the frame right on 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 new orange elastomer collet expands outward to a precise machined limit evenly dispersing pressure in your frame shell for a super snug fit.

This design is on all of our BB30, PF30 and BBRight bottom brackets.

Expanding Orange Elastomer

With both cups connected and our elastomer expanded, there is no chance the bearings can come out of alignment or 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.
