BK-6034 - BSA Thread-In, ABEC-3, Bottom Bracket for BSA framesets and Shimano (24mm) Cranksets

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.

Finding the right bottom bracket for the ever-growing range of bicycles on the market is not always an easy task. At Enduro we currently offer over 50 different types of bottom brackets for various bottom bracket shell and crankset combinations in multiple price/performance levels. Enduro bearings offers threaded options for BSA, BSA 30, Italian and the robust T47 system. For pressfit bottom brackets we have thread-together Torqtite bottom brackets. We even offer flanged, double-row bearings to fit 30mm cranksets in BB86 shells!
