COMPATIBILITY NOTES
Bottom Bracket
The Girder Carbon M30 mountain crank requires the use of a Praxis M30 Bottom Bracket as it has a 30mm drive bearing, and a 28mm non-drive bearing unique to Praxis. Please choose from the M30 options above for your specific frame spec.
DM Ring
We make two versions of our DM rings for correct chainlines “DM-A” or “DM-B”.
When installed on a Praxis mtn crank: DM-A = 49mm NON-BOOST Chainline.
When installed on a Praxis mtn crank: DM-B = 52mm BOOST Chainline.
Praxis MTB rings work great with both Shimano and SRAM 10sp and 11sp chain and drivetrains.
THESE CRANKS DO NOT COME WITH THE REQUIRED INSTALLATION TOOLS, PLEASE ORDER SEPARATELY.
Note: Chainline is critical. Do NOT install another brand DM ring on a Praxis Mtn crank as the chainline will not be correct 49mm or 52mm Boost.

Singletrack
For Praxis’ first carbon fibre crank, the Lyft is an exceptionally well-made piece of kit. … span smoothly and quietly throughout testing, and its gorgeous carbon fibre construction means it is one of the lightest on the market.
