BK-6034 BSA Bottom Bracket

Enduro's entry level BB solution, though many steps up when compared to other products on the market. This complete bottom bracket includes ABEC-3 radial bearings in USA-made, precision-machined aluminum cups that thread directly into the BB shell, along with a machined aluminum center sleeve and seals to protect the bearings from the elements, and selection of spacers to allow you to precisely tune your chain-line. This thread-in solution allows you to fit your Shimano 24mm cranks into your BSA threaded bottom bracket shell without any hassle. Enduro ABEC-3 bearings feature 52100 High-Carbon Chromium alloy races paired with grade 10 Balls, LLB seals and 90% fill high-pressure, water-proof grease. Enduro engineers all of our radial bearings with deeper grooves to accommodate the largest balls possible, providing maximum bearing contact area and greatly increased bearing life.
