Bottom Bracket supports 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; design optimizes bearing load, minimizes drag, and boosts durability
Alloy cups and steel bearings and English threading; 68- or 73-millimeter shell width, 119-gram weight, and sealed cartridge bearings
Includes limited two-year manufacturer's warranty
