SRAM GXP Bottom Bracket, Team Cup Italian 70mm

The SRAM GXP Team bicycle bottom bracket is durable, lightweight and designed to support SRAM road or Truvativ mountain cranksets, and is identical to bottom brackets used in popular Force and X0 groups. Left side bearing has smaller diameter to mate with stepped spindle of SRAM crank, allowing inner race of left side bearing to be captured between crankarm and spindle. Right side bearing "floats" on spindle, handling only radial loads as you pedal. The SRAM design optimizes bearing load, minimizes drag, and gives you durability. The GXP Team Bottom Bracket has alloy cups and sealed cartridge bearings to keep dirt and water out for a maintenance-free experience.
