  • These BBInfinite Threaded GXP Bottom Bracket Cups work with all GXP-standard road crank sets on the market, be it Sram, Cobb, 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) of this road bike bottom bracket features an anodized, precision machined bushing and anodized alloy bearing shield. This threaded bottom bracket installs with the common Park Tools BBT-9 bottom bracket wrench.
