Cema Bb30a Shimano Bottom Bracket Cups

CEMA BB30A Shimano Interlock Bottom Bracket for CannondaleUnlock the full potential of your Cannondale bicycle with the CEMA BB30A Shimano Interlock Bottom Bracket. Engineered for cyclists who demand silent performance, uncompromising stiffness, and superior efficiency, this bottom bracket is the definitive upgrade to eliminate common press-fit issues and enhance your ride quality. Designed specifically for the unique demands of Cannondale´s asymmetric BB30A frames, this component provides a flawless interface between your frame and your Shimano crankset.Experience a Silent, Powerful RideThe core of this premium bottom bracket is CEM´s innovative Interlock technology. Unlike standard press-fit cups that can shift or misalign under load, the Interlock design features two precision-machined aluminium cups that thread securely into each other inside the bottom bracket shell. This creates a single, solid unit that braces the frame, preventing any movement and permanently eliminating the frustrating creaks and pops associated with press-fit systems. The result is unparalleled stability, improved frame alignment, and a significant increase in stiffness for more direct and efficient power transfer. Every watt you produce goes straight to the drivetrain, not into flexing or noisy components.The Advantage of Ceramic BearingsAt the heart of this system are CEM´s SRC Ceramic bearings, renowned for their exceptional performance. These high-grade ceramic balls are significantly harder, smoother, and lighter than traditional steel bearings. This translates into an incredibly smooth and frictionless pedal stroke that saves you precious watts on every climb and acceleration. Ceramic bearings are also highly resistant to corrosion and require less lubrication, ensuring long-lasting performance and reduced maintenance, even when exposed to the harsh conditions of MTB Cycling. From dusty trails to wet roads, you can count on consistent, top-tier performance.Built to withstand the rigorous demands of both road and MTB Cycling, this bottom bracket features robust aluminium dust covers that provide an effective seal against dirt, water, and grime, protecting the high-performance bearings within and ensuring a long service life.This CEMA Interlock bottom bracket is engineered for a perfect fit on asymmetric Cannondale frames.* Frame Standard: BB30A Asymmetric Cannondale* Frame Shell Width: 73 mm* Frame Inner Diameter: 42 mm* Crank Type: Shimano (24 mm axle)* Axle Diameter: 24 mm* Bearing Type: CEMA SRC Ceramic (Also available with Stainless Steel bearings)* Material: Aluminium Cups and Dust Covers* Available Colours: Black, Red* Application: Road, MTB Cycling
