Service Course B2 Seatpost

The introduction of Zipp’s new Service Course line is a welcomed bit of relief from the black hole-esque dream-state we’ve been in with cycling’s carbon era. The Service Course B2 Seatpost, in Zipp’s new silver-finish, throws back to the classic, exposed steel and aluminum that soared to some of the greatest victories in the golden age of cycling. Designed with zero and 20mm offset positions, the Service Course B2 is ready for on and off-road miles and the two-bolt adjustability makes install and fine-tuning easy and convenient.

  • Brilliant new silver-finish for Zipp's trusted Service Course line
  • Stand out from the carbon-crowd on the lunch rides
  • Proven performance and durability for extended use
  • Offset position available for ideal fitting

Perfect Saddle Holder Tool

I've put it through the wringer
True to size

This bad boy holds my saddle like a pro! It hasn't moved ever since I torqued it down! I would recommend this product if you want to keep your saddle in the same position and at the same height!


Will this seatpost support a saddle with 7x9mm carbon rails?
