BKSM-8133 - Maxhit, Stainless Steel 440C, T47 DUB/29mm - Maxhit is the latest patented innovation from Enduro, where the bearing is actually the component. The Maxhit bottom bracket rings are designed to be screwed directly into the shell of your bottom bracket, eliminating the need for traditionally used aluminum covers to support the bearings. This unique design allows for much larger balls, doubling the load capacity compared to standard BB bearings. The kit includes a complete selection of seals and spacers to ensure proper installation on any T47 threaded bike. Made entirely from stainless steel 440C and guaranteed for life, the Maxhit BB bearings feature proprietary double-lip labyrinth seals as well as excellent high-pressure grease from Enduro, ensuring robust and trouble-free performance throughout their lifespan. Enduro's bearing range starts with chrome steel, black oxidized in type A/C, and then offers stainless steel 440C at the top. They are always made with the largest possible balls and double lip seals that run in a micro-groove profile to provide ultimate protection against sweat and weather conditions. They are filled 90% with high-pressure water-resistant grease, so you never have to guess if there is grease inside. Enduro's angular contact bearings (A/C) have all active balls to distribute the force over a larger area, are waterproof, and minimize wear.
