"BKC-0776 - T47-Threaded, Ceramic Hybrid, XD-15, Angular Contact Bearing, Bottom Bracket for T47 Framesets and 30mm CranksetsEnduro Bearings presents the T47 - BB - XD15 Pro - 30mm, a high-performance bottom bracket designed for T47 framesets and 30mm cranksets. This top-of-the-line BB bearing kit includes Enduro's XD-15 Ceramic-Hybrid, ABEC-5 bearings, as well as all necessary seals and spacers for a precise and professional installation.Our XD-15 Ceramic-Hybrid bearings are an exclusive product, combining corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride Grade 3 ceramic balls. This proprietary process results in the ultimate high-performance bearing setup. The deep-groove design raceways allow for maximum-sized Grade 3 Silicon Nitride ceramic balls, increasing contact area and improving performance and longevity.The XD-15 bearings are lubricated with 90% fill Kluber NBU52 grease, which becomes smoother and better with time. This grease is highly resistant to being washed out and is engineered to stick to the balls, continually being pulled back into the ball path where it is most needed. Unlike other bearings, XD-15 bearings actually become smoother as they wear-in, providing superior performance over time.We are so confident in the quality of our XD-15 bearings that we offer an unlimited lifetime bearing and race warranty. For easy removal and installation of this bearing kit, we recommend using the BRT-003 (eb9040) 24mm x 37mm bearing tool. With just a few twists of the wrist, the BRT-003 allows for quick removal and installation of bearings while the bottom bracket is still on the bike.Shell Fitment: T47Bearings: XD-15 CeramicSeal Type: LLBGrease: Kluber NBU52 GreaseAxle Size: 30mmWarranty: Unlimited LifetimeEnduro Reference Number: BKC-0776"
