Bike Bottom Brackets: The Silent Heart of Your Drivetrain
The bike bottom bracket (BB) is the unsung hero of your bicycle. It houses the bearings that allow your crankset to rotate smoothly. Because it sits at the lowest point of the frame, it is constantly bombarded by dust, water, and grime. Upgrading to a RIDERACE bottom bracket ensures high-efficiency power transfer and a silent, creak-free ride.
Understanding Compatibility and Standards
The world of BB standards can be confusing, but it boils down to two main types:
-
Threaded (BSA/English): The most reliable standard. These cups screw into the frame, making them easy to service and remarkably resistant to creaking.
-
Press-Fit: Common in modern carbon frames. These require precision-engineered tolerances to stay quiet. Our press-fit range features high-grade seals to prevent the "creak" often associated with these systems.
Bearing Materials: Steel vs. Ceramic
-
Stainless Steel: The best choice for 90% of riders. It offers a perfect balance of smooth rotation, longevity, and resistance to corrosion.
-
Ceramic: For racers looking for every marginal gain. Ceramic bearings offer lower rolling resistance and can be harder than steel, though they require more frequent maintenance.
Maintenance and Lifespan
A gritty or "notchy" feeling when you spin your cranks is a sure sign your bearings are shot. Our bottom brackets utilize double-lip labyrinth seals to keep grease in and contaminants out, significantly extending the service interval even in wet riding conditions.
