Campagnolo EPS V3 Power Unit Seatpost Adapter
The reduced diameter (16.6 mm) allows the V3 Power Unit to be mounted within the seatpost, by using one of the two available adapters (for ø 27,2 and ø 31,6 mm), thus reducing assembly time.
  • For 27.2mm and ø 31.6mm posts
  • 16.6mm
  • V3 Compatible
A must with all V3 setup. Make sure to pick the right size for your seat post. V3 battery is longer than Di2 so you want to make sure your V3 battery stays inside your seatpost properly.
