praxis works Girder Carbon M30 - Direct Mount Crankset - 52mm Boost - 32 Teeth - black

Symbolic picture: For illustrative purposes the product is shown in another color or variation.

The all new Girder Carbon sets its sights to become the go-to crank for the Trail / Enduro world. With the combined benefits of a wide bearing stance, 30mm aluminum spindle, and now lightweight carbon arms, this is a fantastic upgrade for any bike and rider.

Wave™ Tech
The Wave™ tooth pattern swings right to left alternating lateral force to each chain link to actively retain the chain. This design creates more open areas for mud and debris evacuation and preserves chain retention in adverse conditions.

• Carbon arm construction
• 3-bolt direct mount ring interface
• 52mm BOOST Chainline
• M30 Spindle | Requires Praxis M30 BB
• Wave™ Tech tooth profile for better chain retention
• Works with 10/11/12sp chains
• Q-Factor: 172mm

Note - Chainline is critical:
Do NOT install another brand DM ring on a Praxis Mtn crank as the chainline will not be correct.

Note - Bottom Bracket:
The Girder 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. Matching M30 Praxis Works bottom brackets will offer compatibility with nearly every frame out there: BSA, BB90/92, BB30, PF30 and even T47 bottom brackets are available.
