Zipp SL70 Seatpost
The Zipp SL Speed Seatpost has taken Zipp engineering a step further, and the result is a seat post that is 48 grams lighter than the Service Course but with the same durability. The SL Speed features the same adjustable, low-profile clamp system as is popular on the Service Course. It is a two-bolt system that provides adjustment both fore and aft and in the tilt of your saddle. You’ll also notice that the lower portion of the clamp is beefier than other seatposts on the market. This provides extra support for those riders who prefer a more rearward position.
