BSA English Threaded GXP External Bearing MTB Bottom Bracket
Info Installation Instructions Installation Video Specifications The BBInfinite BSA Threaded GXP External Bearing Bottom Bracket Cups work with all GXP-standard MTB cranksets on the market, be it Sram, Quarg, and all others. Alloy bottom bracket cups are MilSpec MIL-A-8625 Type II anodized for extreme durability. On the drive side, a polymer labyrinth seal bearing cover with integrated bushing keeps out dirt and debris while isolating the steel bearing races from the steel spindle, halting creaks, corrosion, and accelerated wear of the crank spindle itself. The spline side (non-drive side) features an anodized, precision machined bushing and anodized alloy bearing shield. The GXP BSA external bearing bottom bracket is installed with common socket-style, 16-notch tools such as the classic Shimano TL-FC33, Park Tools BBT-69.2, and many others. Spacer kit included with threaded BSA bottom bracket. ABOUT OUR BEARING CHOICES: Ceramitech Bearings: Our Si3n4 hybrid ceramic bearings fea
