Praxis Alba M30 Crankset 10/12V 172,5mm 50/34T - Black

Deep in the hills of Santa Cruz, cyclists are brought to their knees by a challenging four-mile climb with an elevation gain of 1800 feet known as Alba Road. This respected climb inspired the Alba Road crank. With beautifully forged aluminum arms combined with the M30 bottom bracket system, the Alba is ready for anything you encounter. Additionally, the cold-forged chainrings feature LevaTime II® shifting technology for faster and smoother gear changes.

Cold-forged chainrings.
All Praxis Works chainrings are manufactured using a patented cold forging process that allows for more complex shaping of the tooth profile. This so-called "one-shot" process enables the company to increase the number of shifting aids on the ring, which is nearly impossible with standard CNC production. The process, requiring over 1000 tons of pressure, creates an extremely hard and tough surface for maximum durability. Individual tooth profiles, changing tooth angles, synchronized paths, and strategically placed shifting ramps are the features that ensure smooth shifting. All of this results in one of the most durable and smoothest chainrings ever produced for cyclists.

LevaTime II
LevaTime® is the result of years of intensive testing and fine-tuning. The end result is one of the best and fastest shifting systems that the gearing industry has to offer. With a LevaTime® chainring, multiple shifting aids are strategically placed for perfectly timed upshifts and downshifts. Synchronized shifting paths are aligned with the inner chainring, providing a clean channel for the chain. Each tooth is individually shaped to perform a specific task. Together with precisely placed rivets, the chain is optimally controlled, effectively preventing chain suck.

Note: The axle tapers from 30 mm to 28 mm. The M30 Praxis Works bottom bracket is required for this. Delivery includes: left and right crank arm with M30 axle and LevaTime II chainrings and spider.
