Praxis Works Alba M30 Direct Mount Crankset - 1x10/11/12-speed - 40T

Praxis Works Alba M30 Direct Mount Crankset - 1x10/11/12-speed - 40T

Deep in the Santa Cruz hills, cyclists are brought to their knees by a wicked four-mile, 1800-foot climb called Alba Road. This respected climb was the inspiration for the Alba road crank. With shapely forged aluminum arms combined with the M30 bottom bracket system, the Alba is ready for whatever you're racing against. In addition, the cold forged chainrings feature LevaTime® shifting technology for faster and smoother shifting.

Cold forged chainrings

All of the praxis works chainrings are manufactured using a proprietary cold forging process that allows for more complex tooth profile shaping. This so-called "one-shot" process enables the company to increase the amount of shifting aids on the blade, which is almost impossible with normal CNC manufacturing.

The process, which uses over 1,000 tons of pressure, allows for an extremely hard and tough surface for maximum durability. Custom tooth profiles, alternating tooth angles, synchronized lanes, and tactically placed shift ramps are the features that provide smooth shifting. All of this creates one of the most durable and smoothest chainrings ever produced for cyclists.



LevaTime® is the product of years of intensive testing and fine-tuning. The end result is some of the best and fastest shifting the gear industry has to offer. With a LevaTime® chainring, multiple shift aids are strategically placed to provide perfectly timed upshifts and downshifts.

Synchronized shifting lanes are aligned with the inner chainring to provide a clean channel for the chain. Each tooth is individually shaped to accomplish a specific task. Together with precisely located rivets, the chain is optimally controlled and chainsucks are effectively prevented.


Alba M30 compatibility

The Alba can be installed with the corresponding praxis works bottom brackets on BSA, BB86, BB30, PF30 or Specialized OSB frames and is compatible with Shimano 10-/11-speed (also Di2), SRAM 10-speed and SRAM 22 11-speed as well as Campagnolo 10-/11-speed (also EPS) drivetrains. The manufacturer recommends the use of a Shimano, KMC or Campagnolo chain.

Note: The axle tapers from 30 mm to 28 mm. This requires the M30 praxis works bottom bracket.
