This press-fit kit enables direct installation of 30mm cranks into BB86/92 frames. Given the narrow 41mm inner diameter of the BB86/92 shell, accommodating a 30mm spindle—only 11mm wide—demands a precise engineering approach. By using flanged double-row bearings pressed into the bottom bracket shell, this design increases the contact surface and doubles the ball count per side, ensuring a durable and reliable fit within the confined space.
This distinctive Enduro XD-15 Pro BB kit incorporates XD-15 Ceramic-Hybrid cartridge bearings pressed directly into the BB shell. The deep-groove raceways accommodate large Grade 3 Silicon Nitride ceramic balls, enhancing contact area for superior performance and extended durability.
Bike Radar praised the XD-15 as "undoubtedly the best bottom bracket we have ever tested." Confident in its performance, we back it with an unlimited lifetime bearing and race warranty. Unlike other bearings, the XD-15 improves with use—its balls polish the races during break-in, resulting in smoother operation over time. While competing ceramic-hybrid bearings may offer initial speed and power benefits, Enduro XD-15 bearings not only match these from the start but continue to enhance efficiency and smoothness as they break in, unlike alternatives that degrade.
Selecting the appropriate bottom bracket for the expanding variety of bicycles can be challenging. Enduro provides over 50 different bottom bracket models designed to fit diverse shell and crankset configurations across multiple price and performance tiers. Our range includes threaded options for BSA, BSA 30, Italian, and the durable T47 systems. For press-fit designs, we developed the widely imitated thread-together Torqtite bottom brackets, along with press-fit Delrin Cup variants. Additionally, we supply flanged, double-row bearings engineered to accommodate 30mm cranksets within BB86 shells.Find your bottom bracket solution here!
