Zipp Service Course SL Seatpost, 31.6mm, 400mm, Offset: 0mm, Black

Specifically tuned to be more shock absorbing than the “comfort” seatposts on the market, while still passing our strict internal MTB strength test. Flex engineered into the light weight carbon tube keeps the rider comfortable over any terrain. Secure, two-bolt clamp makes for easy micro-adjustments of saddle position, and the head has been redesigned for maximum bolt head accessibility.
