bb30 press-fit pro-tech cups 68x42

The Ekar bottom bracket is designed specifically for gravel and all road riding. Featuring a patented ProTech- system with an external sealing ring and internal sleeve protects from water, grit and dirt ingress. Oversized, protected external stainless steel bearings attach directly to crank arms for a smooth, fluid performance. The bottom bracket mates with the external stainless steel bearings which are attached to the crank arms as an integral unit rather than the BB cups for greater size and easier maintenance access and sits over a stiff, strong inner axle spindle, delivering a performance that is smooth, fluid and predictably consistent from the get-go. Thanks to the Pro-Tech sealing system, it stays that way, however and wherever you ride. Ekar bottom bracket options offer broad compatibility in a full range of threaded and PressFit applications. **Technology** * ProTech system: Patented dual-sealing ProTech technology securely connects the two semi-axles inside the bottom bracket, and protects the BB bearings from ingress of water and mud, providing longevity of high performance, even in the worst riding conditions. A gravel orientated development from Campagnolo's innovative and proven Ultra-Torque technology, the ProTech system's central Hirth joint features self centering and self aligning frontal teeth located in the middle of the crank where the ends of the integrated semi axles meet. * Oversized, protected external bearings: for smoothness **Specification** * Designed specifically for Ekar 1x13 groupsets * Suitable for Gravel and All-Road riding * Full compatibility with all threaded and PressFit standards (BSA, ITA, BB86, BB30, BB30A, BB386, PF30, BB Right, T47) * Weight: 50g
