CAMPAGNOLO EKAR PRO-TECH INTEGRATED BOTTOM BRACKET : BB386 86.5x46

The new Campagnolo Ekar bottom bracket is designed specifically for the rigors of all-road and gravel riding and racing.   This new bottom bracket 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 that are attached to the crank arms as an integral unit rather than the BB cups for greater size and easier maintenance access. It 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.   * NOTE requires Campagnolo tool UT-BB140 for installation (or equivalent) interface  BB386 86.5 x 46
