PF30/BB30 to Shimano Bottom Bracket Adaptor - 73mm (Ex-Demo / Ex-Display). This is an ex display Bottom Bracket which has some minor cosmetic marks. Please see image.
This is the Praxis Works PF30/BB30 to Shimano Bottom Bracket Adaptor - 73mm. Praxis' conversion bottom bracket is designed to be a proper bottom bracket for Shimano Hollowtech cranks in PF30 and BB30 frames. This includes the PF full sleeve which your remove if your frame is BB30. Their patent pending design maintains the cartridge bearing outboard of the frame right on Shimano spec for greater rigidity and free of frame -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, Praxis' 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.
Praxis' unique collet system also greatly reduces the chances for creaking and other unwanted noises associated with the lesser ''Band Aid/Spacer'' type adaptors in the market. The cartridge bearings are high quality steel with shield-type quad-ring seals. The Praxis Works Conversion Bottom Bracket is the most rock-solid BB for Shimano cranks on PF30 frames.
