The Zayante Carbon-GR takes Praxis's lightweight Zayante carbon arms and sets them up for gravel. The wider chainline lines up with Shimano GRX 2x and SRAM Wide front derailleurs, or you can run it 1x on the 3-bolt direct-mount interface.

Highlights

  • C.R.A.F.T. carbon arms: 418 g for a 172.5 mm arm set
  • Gravel chainline: 47 mm for 2x, 48 mm for 1x
  • 48/32 lightweight LevaTime II X-rings with alloy bolts, or a 38, 40 or 42T 1x ring
  • M30 alloy spindle (30 mm drive / 28 mm non-drive)
  • 150 mm Q-factor

Made for gravel groups

Shimano GRX 2x and SRAM Wide front derailleurs sit further out than road ones, so the Carbon-GR moves the rings out to a 47 mm chainline to match. With a 1x ring on the direct-mount interface, the chainline is 48 mm. If your bike uses a standard road front derailleur, Praxis recommends a road crank instead.

The arms are the same C.R.A.F.T. carbon arms Praxis makes in-house for the Zayante road crank.

Compatibility & fit

Bottom bracket: needs a Praxis M30 bottom bracket (30 mm drive / 28 mm non-drive bearing), sold separately: BSA, BB86, T47 internal bearing, T47 external bearing, BB30, PF30, 386EVO or BBright.

Drivetrain: Shimano GRX (Di2 and mechanical) and SRAM Wide (eTap and mechanical), 10/11/12-speed; KMC, Shimano and SRAM chains including Flattop. 1x setups need a clutch rear derailleur and are not for Campagnolo chains.

Power: Praxis lists 3-bolt spider meters from Power2Max (NG and NG Eco), SRM, SIGEY and XCADEY, plus power pedals.

The Tune Cycles workshop can fit the bottom bracket and crankset for you as a separate workshop service. Threaded shells need the right BB tool and press-fit shells need a proper bearing press, so it pays to have the shell checked and the bottom bracket fitted correctly first. The main crank bolt is torqued to 48–52 Nm with a torque wrench.
