We know what you're thinking holy cow, another bottom bracket standard. We hear you the choices for headset and bottom bracket standards are already staggering. However, if you look at the reasoning behind BB386, it really does make sense. An 86mm bottom bracket shell gives frame designers more room literally to innovate down tube and chainstay design, because the added width opens up an area for tube size and shape manipulation. Wilier was the first company to climb on board. The Wilier 386EVO Bottom Bracket Adapter makes your Wilier frame compatible with this new bottom bracket standard, and works with either Shimano or Campagnolo component groups. The adapter kit comes with eight components: two frame cups, two 6805RS sealed cartridge bearings, two spindle adapters, one wave washer, and one locking pin. The components that you use will depend on whether you're using Shimano or Campagnolo components.
