BBright™ is a new bottom bracket dimensional standard for bicycle frame and cranks.
BBright™ provides a great combination of performance and reliability. BBright™ maintains existing chainline and pedal stance width dimensions (sometimes called Q-Factor), thus maintaining compatibility with existing drivetrain standards and riding position. BBright™ also maintains compatibility with existing crank accessories such as crank spider-based power meters. BBright™ requires only a minimum of retooling for crank and frame makers.
