Praxis Girder Carbon Cranks

Get some carbon bling at an aluminum price.

Praxis has yet another entry into the carbon cranks realm – and this one won’t break the bank. Unveiled at the Sea Otter Classic last month, the Girder Carbon 1x crankset has a claimed weight of 542 grams and sells for $310 including protective crank boots and chainring, which comes in 30, 32, 34, and 36-tooth options. Extra rings run $50-$60.

Chain retention is achieved via Wave tooth technology, which Praxis claims has been shown to deliver longer life and fewer chain drops compared to the more widely used narrow-wide system.

Nearly all the BB types are covered.

The lightweight carbon arms are held in place with a 3-bolt direct mount interface, and overall strength is enhanced by the use of a massive 30mm spindle that steps down to 28mm on the non-driveside, thus staying in place without need for a lock-ring or any guess work on appropriate pre-load force. And the M30 BB fits MTB frames with BSA threaded, BB90/92, BB30, PF30 and T47.
