The people's seat post.

The Zipp SL Speed Seatpost was a favorite of pro's and amateurs alike, both on those long rides through the mountains and at the starting line of 'cross races. Redesigned for 2017, the Zipp SL Speed B1 Carbon Seatpost benefit from their partner SRAM's Exogram™ technology, making this as light and strong as possible. Further improvements include a redesigned clamping system to provide even greater adjustability, security, and ease of use. To truly make this seatpost the people's choice, the SL Speed B1 is now available in either 0º or 20º offset versions.

Weighing in at just 170g for the 0º or 172 for the 20º, both available in two diameters: 27.2mm or 31.6mm.

Great seat post with compliance, strength, and light weight
by Anonymous

Upgraded from Zipp Service Course post to this post and immediately noticed a difference in the compliance while riding. The post is stiff but also has a lot of compliance to absorb all the road noise.

Lightweight and simple to adjust

This post is lightweight, comfortable, and the single bolt design is surprisingly easy to adjust without any slippage issues. A bit pricy, but in line with similar offerings. Does use a T25 Torx bolt which can be a turn off for some people.
