The new Ekar bottom bracket is designed specifically for the rigors of all-road and gravel riding and racing.

It features the robust double-protection of Pro-Tech™ -– a patented external sealing ring design protecting a strong, resilient fiberglass-charged polyamide central tube from the harmful ingress of water, mud and grit. 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 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.
