CHAIN RING QUESTIONS
If the timing is off by incorrect mounting or you substitute a different ring than the matched combo, the shift quality will degrade and problems will occur. Do NOT substitute any other ring type or tooth count into your Praxis matched pair.
Also, our rings shift great with SRAM 10sp drivetrains and the new SRAM 22 11sp drivetrains. Yaw Front derailleurs work great with our rings too.
Please read our full Compatibility Statement Here.
CATCH PIN - The Big Ring chain catch pin sticks out too far and touches the back of my crank arm. What do I do?
LOOK ZED RINGS - I have a bicycle with the ZED crank, can I buy the custom Praxis forged ZED Chainrings from you?
Please use one of the 3 brands we suggest for the designed shifting experience with Praxis Works LevaTime chain rings.
BOTTOM BRACKET QUESTIONS
- Shimano Conv BB- Current versions use an Enduro 2437 bearing with our current orange outer seal. Older versions used a 6805 bearing with black plastic end/spindle reducer cap.
- SRAM GXP/ISIS2 Conv BB- uses an Enduro 2437 bearing for drive side, and 2237ER w/Extended race on the NonDrive side.
Choice 1: If you want warranty/support, you will simply purchase a new BB.
Choice 2: If you don’t care about warranty, then you can just pull/repress a new Enduro 2437 bearing. We just have to be clear that when you do this modification, the Praxis warranty has been voided.
- Shimano Conv BB – Current versions use an Enduro 2437 bearing with our current orange outer seal. Older versions used a 6805 bearing with black plastic end/spindle reducer cap.
- SRAM GXP/ISIS2 Conv BB – uses a 2437 bearing on the drive side, and a 2237 w/Extended race on the NonDrive side.
Specialized OSBB - Will your Conversion BB work on my Specialized OSBB road bike? IE Venge... Roubaix... Tarmac.
We now have versions for both SRAM/GXP and Campy ULT.
CRANK COMPATIBILITY QUESTIONS
IMPORTANT – Our chain rings are 10sp and 11sp compatible, so you can use our rings with a Campy 10/11sp drivetrain if the rings are mounted on a traditional 5-arm mount 110 or 130BCD crank. For example, you could use cranks by Specialized, LOOK, Cannondale, FSA, ROTOR, Quarq, etc. Many people use these cranks with our rings, with the rest of the drivetrain Campy 10 or 11.
