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.
