Advent calendar / raffle: The Praxis Works cranks have become increasingly popular in recent years. The Alba line is specially designed for racing bikes. The name comes from a 6,4-mile, 550-foot climb called Alba in the hills of Santa Cruz, California. This dreaded climb inspired Praxis Works to create their Alba Road crank with solid forged crank arms and M30 axle system.
Practice Works Alba Road Crank is equipped with the most important Praxis Works technologies and features and has a wide supporting M30 aluminum axle and forged crank arms, which should ensure a light and stiff drive. The chainrings, which are cold-forged before milling, impress with their durability and can be shifted extremely quickly and efficiently thanks to the elaborately calculated LevaTime tooth profile, which has been continuously refined over the years. The direct mount spider attachment allows easy conversion to simple if required.
Practice Works Alba Crank Technologies
Praxis Works used all its know-how to develop the Alba crank. First and foremost, the crank was matched to the chainrings and the bottom bracket. Here you could also benefit from feedback from professional sports.
The Praxis Works Alba crank is the result of a 2D forging process. The metal is subjected to massive pressure, resulting in light, strong and very durable crank arms.
Cold forged chainrings
Praxis Works chainrings are cold-forged because they can be used to create unique tooth shapes and climbing aids. 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 switching precision and a long service life. The individual angles of the teeth and the additional climbing aids for the gears make these chainrings unique.
LevaTime
The LevaTime shifting technology developed by the engineers in long series of tests plays a large part in the high shifting comfort of the Praxis Works chainrings. Both chainrings are adapted to each other and coordinated, right down to an individual shape for each individual chainring tooth.
M30 bottom bracket
Praxis Works M30 bottom brackets are only suitable for use with Praxis Works M30 cranks. The M30 axis corresponds to a kind of "Oversize GXP". It is 30mm thick and reduced to 28mm at the left end to fit the non-drive side bearing. M30 combines the advantages of wide bearings with the advantages of a burly 30mm axle. This enables a secure fit and better power transmission.
The matching M30 bottom bracket from Praxis Works allows the crank to be used in almost any frame: BSA, BB86, BB386Evo, BB30, PF30 and even T47 and BBRight bottom brackets are available.
