The BB30 - TorqTite - 440C Stainless Steel - DUB 29mm by Enduro Bearings is a stainless steel bottom bracket designed for BB30 framesets and SRAM DUB 29mm cranksets. This innovative product features Angular Contact Stainless Steel bearings that are pressed into precision machined aluminum TorqTite cups. These cups thread together in the BB shell for a secure and creak-free installation. Made to the highest standards at the Enduro Bearings production facility in California, USA, this bottom bracket is built to last. The 440C stainless steel balls and races provide superior corrosion resistance and long life. While stainless steel has slightly less load capacity and is softer than our standard chromium steel, it is a great alternative for wet conditions or where sweat can be a problem. To further protect against the elements, we use LLB type seals and CRC marine grease in these bearings. We are so confident in their quality and performance that we provide a three-year anti-corrosion guarantee.Finding the right bottom bracket can be a challenge, but Enduro Bearings offers over 50 different types to suit various bottom bracket shell and crankset combinations. We have threaded options for BSA, BSA 30, Italian, and the T47 system. For press-fit bottom brackets, we have the thread-together TorqTite bottom brackets and press-fit Delrin Cup options. We even have flanged, double-row bearings for 30mm cranksets in BB86 shells.Shell Fitment: BB30Bearings: 440C Stainless SteelSeal Type: LLBGrease: Kluber CRC Marine GreaseAxle Size: SRAM DUB 29mmWarranty: 2 yearsEnduro Reference Number: BKS-0181
