- Supplier Warehouse In StockUsually dispatched within 3-5 business days
Enduro offers a reliable entry-level bottom bracket that outperforms many competitors. This complete unit features ABEC-3 radial bearings housed in precision-machined aluminum cups made in the USA, which thread directly into the bottom bracket shell. It includes a machined aluminum center sleeve and protective seals to shield the bearings from dirt and moisture, plus a range of spacers for fine-tuning your chainline. Designed as a threaded solution, it seamlessly accommodates Shimano 24mm cranks in your BSA threaded bottom bracket shell with ease.
Enduro ABEC-3 bearings are constructed using 52100 High-Carbon Chromium alloy races combined with grade 10 balls, LLB seals, and a 90% fill of high-pressure, waterproof grease. Designed with deeper grooves to fit larger balls, these radial bearings maximize contact area, significantly enhancing durability and extending bearing lifespan.
Selecting the ideal bottom bracket for the diverse and expanding range of bicycles can be challenging. Enduro provides over 50 different bottom bracket models tailored to various shell and crankset combinations, covering a spectrum of price and performance options. Their lineup includes threaded solutions for BSA, BSA 30, Italian, and the durable T47 systems. For press-fit applications, Enduro developed the widely imitated, thread-together Torqtite bottom brackets alongside press-fit Delrin cup options. Additionally, they offer flanged, double-row bearings designed to accommodate 30mm cranksets in BB86 shells.
