Interloc Racing Design's premium JIS square-taper bottom bracket features Japanese sealed-cartridge bearings, a hardened SCM415 cro-mo spindle, 6061 aluminum cups, a beautiful polished finish and whopping ten-year warranty.

Pro tip: The crankset being used determines spindle length, not the frame. Please check what length the manufacturer recommends for your crankset or measure your existing BB's spindle.
