Wilier sagt BB93 ....was wohl eine extrawurst ist


OVERSIZE BOTTOM BRACKET

Wilier's exclusive BB93 has been an innovative technology since its original introduction, now proven over several years.
The oversize bottom bracket shell that measures 93mm in width, in combination with a specially designed bottom bracket, increases frame stiffness while providing compatibility with all major crankset brands. Add to this technology the superior stiffness of its fork, and the TwinFoil stands out even more in terms of efficiency and precision handling.
