Praxis Works Conversion Ceramic Bottom Bracket
Allows you to use a Shimano hollowtec 2 crank with a frame that has a BB30 or PF30 bottom bracket shell.
Bearings remain outside of the frame and exactly to Shimano spec. This places the load in the correct location on the spindle. With the left cup and right cup connected, the BB can't wiggle out, fall out, or come out of alignment like other current adaptors in the market.
The Praxis design is unique and with it's collet expansion also greatly reduces the chances for creaking and other unwanted noises associated with the lesser "Band Aid" type adaptors.
For Shimano Hollowtech II cranks
For 68mm BB30 or PF30 frames only. (NOT FOR BBRight or BB386EVO)
NOT FOR MTB CRANKS.
Included Delrin Sleeve used for PF30 frames.
