TRIPEAK BB30 oval chainring

B-Labs chainrings have been developed to evolve the concept of the single chainring drivetrain.

These chainrings are designed to be mounted as a single chainring in the search for a simpler, lighter and more effective drivetrain.

The evolution brought by B-Labs oval chainrings is due to the fact that with a single chainring, we are able to have 3 virtual developments, giving us two more teeth on the hardest gears and removing 2 teeth on the lightest gears.
