Planning on some drivetrain upgrades for the new year? Praxis just dropped a few new options that cover the spectrum from high end MTB to heavy duty e-bike use.
First shown in 2017, the Praxis Girder carbon crankset was their take on an “affordable” carbon crankset. Now, the Girder Carbon G2 crankset builds on that premise with more shapely arms that are designed to offer better frame clearance – not to mention they’ve actually gotten less expensive.
Still using their M30 spindle which requires the use of the Praxis M30 bottom brackets. the spindle uses a 30mm drive side bearing and a 28mm non-drive.
Also updated is the 3 bolt direct mount chainring interface which has been adjusted to work with established chainline offsets. The crankset now weighs in at 488g without a ring, and they’re available in 165, 170, and 175mm lengths with a 178mm q-factor. Sold without a chainring or bottom bracket, the crankarms are priced at $290.
For those that are particularly hard on components, the Praxis Cadet crankset is now also offered in an HD version. HD of course standing for Heavy Duty with a reinforced arm structure. Otherwise, they’re the same forged aluminum crankset with the Praxis 30mm spindle, self extracting hardware, and direct mount chainring. This one is offered only in 165 and 170mm lengths with a 177mm q-factor and a claimed weight of 640g without a chainring. These are priced at $160 for the pair.
It’s a similar story for the eHD crankset, just with a fitment designed for e-bikes. The ISIS Spline is meant for used with many different e-bike motors, and the HD cranks are offered in extra short 160 and 165mm options with q-factor varying by the motor that they’re mounted to. The HD version of these sells for $85.
Ceramic M30 Bearing Kit
Last up is a new Ceramic option for their M30 bearing bottom brackets. Given the proprietary 30/28mm bearing diameter, you’ll have limited options for replacements, so Praxis now offers ceramic replacement bearings for existing M30 bottom brackets. The rebuild kit only applies to the bottom brackets listed below, and the price is set at $85.
Compatible Bottom Brackets:
- M30-T47 E.B
- M30-T47 I.B.
