The five-arm Buzz Sport Road chainrings from Praxis Works with 110 mm bolt circle diameter are compatible with 10-speed, 11-speed and 12-speed drivetrains. They are cheaper than the conventional Buzz chainrings and are therefore suitable as quick spare parts.

Technology:

Cold Forging Process
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™
LevaTime shifting technology, developed by engineers in long series of tests, plays a large part in the high shifting comfort of Praxis Works chainrings. Both chainrings are adjusted and matched to each other, right down to the individual shape for each individual chainring tooth, so that its shape and angle are synchronized with the partner chainring.
