SRAM Bottom Brackets | BB30 - 42 x 68/73mm

BB30-named for its required spindle size-narrows Q-factor increases ankle clearance, and ups bearing durability. Along with a 30 mm spindle, it requires an oversized 68mm or 73mm bottom bracket shell and PressFit bearings held in place by snap rings.

• Narrow Q-factor
• More ankle clearance
• Larger bearings for longer life
  
  Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability, and stronger crank construction.
