BKSR – 0142 – Torqtite, stainless steel, Radial Bearing Bottom Bracket for BB386 Framesets and Shimano 24mm CranksetsAn Enduro Original, this Torqtite BB solution utilizes 440C stainless steel radial bearings pressed into precision machined aluminum Torqtite cups that simply thread together in the BB shell for a simple, secure, creak – free installation in non – threaded/press – fit BB shells. All Enduro bottom brackets are manufactured to the highest standards at the Enduro Bearings production facility in California, USA.This complete bottom bracket features 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. Though stainless steel has about 20% less load capacity when compared our standard 52100 chromium steel used in most of our bearings, 440C stainless is an excellent alternative for use in wet conditions, if you wash your bike often, or where sweat can be a problem. Enduro stainless bearings also feature full – contact, dual – lip, labyrinth (LLB) seals and Kluber NBU52 high – pressure grease to provide an additional level of protection against the elements. We are so confident in the quality and performance of theses bearings, Enduro provides a three year anti – corrosion guarantee. Finding the right bottom bracket solution for the ever – growing range of bicycles on the market is not always an easy task. At Enduro we currently offer over 50 different models 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 press – fit bottom brackets we created the oft – copied, thread – together Torqtite bottom brackets as well as press – fit Delrin Cup options. We even offer flanged, double – row bearings to fit 30mm cranksets in BB86 shells!
