Praxis Works Alba X M30 Road crankset - faster and more precise shifting

The Alba X M30 DM Road crankset by Praxis Works will master every challenge with you - even that small, mean climb up Alba Road near Santa Cruz, from which the crank gets its name. Alba X comes with the innovative LevaTime II chainrings, which are attached via the sturdy 4-arm X-Spider. LevaTime II means a stiffer, 5 mm thick large chainring, even more forged shifting ramps and redesigned pins that help to achieve faster shifting. You've never changed gears like this before. Thanks to the direct mount, Alba X can of course also be ridden 1x. Please note that this crankset must be combined with a Praxis Works M30 bottom bracket.

Cold Forged Chainrings
The primary reason why Praxis Works chainrings are cold forged is because it allows you to produce unique tooth shapes and shifting ramps. In addition, the one-shot process makes the surface harder and more resistant, which is not possible with CNC chainrings. In practice, the process delivers high shifting precision and long service life. The individual angles of the teeth as well as the additional shifting ramps for the drivetrain make these chainrings unique.

LevaTime™ II
The LevaTime II X-Ring chainrings are an ambitious further development of the first LevaTime chainrings. The large chainring is now stiffer and 5 mm thick, allowing Praxis Works engineers to increase the number of shifting ramps forged into it and improve the type of shifting features. This also made it possible to fit new forged, fast-acting shifting pins, which increase the speed of shifting. All this is held together, now even more stable, by the redesigned forged LT2 X-Spider. As soon as you get to know these new chainrings, you will find them clearly superior to ordinary chainrings. LevaTime II takes shifting to a new level.

Praxis Works M30 bottom brackets are only suitable for use with Praxis Works M30 cranks. The M30 axle corresponds to a kind of " oversize GXP" . It is 30 mm thick and reduced to 28 mm on the left end to fit the non-drive side bearings. A shaft washer is used at the drive side to provide preload and a 30 mm bearing, which is opposed by a 28 mm bearing at the non-drive side. M30 combines the advantages of wide bearings with the benefits of a sturdy 30 mm axle. This enables a secure fit and better power transmission.
