MegaExo bottom brackets offer greater bearing life versus older Isis or Octalink bottom brackets. The ball bearings are 40% larger than most ISIS Drive BB's for greater strength and longevity. Furthermore, the bearings are spaced wider apart for an overall increase in the stiffness of the bottom bracket/crankset interface.

Great price on a great bottom bracket, perfect fit, nice finish, have several hundred miles on this one with no problems yet!
Excellent bottom bracket. My road bike was originally equip with the FSA bottom bracket and I put over 3000 miles on it before bearings started showing signs of wear. So did not even consider another type bracket. Installed quickly without any issues.
