We’ve taken our pro-proven Service Course SL Seatpost and made it better… and lighter. The redesigned post, weighing just 235grams for 20-mm setback and 220 grams for the 0 setback, are lighter while providing security and a precise fit. It’s also designed for easier tool access to the downward facing bolt for easy setup.

Better fit means better performance. If your saddle is out of position, you’ll waste energy with every pedal stroke. The secure, low-profile clamp allows the saddle to slide farther back along the rails, and with 0 mm and 20 mm setback options, it’s possible for nearly any rider to achieve the perfect fit. This unique clamp design also features downward-facing bolt heads that allow micro-adjustment of the saddle even after it is mounted.

For high strength, low weight, and efficient use of every gram, the shaft and head are not bonded but are 3D-forged from a single piece of 7075 aluminum. We use titanium bolts and more intricate machining than the Service Course seatpost.

Available in 27.2 or 31.6mm diameters. The Service Course SL Seatpost is available in 330 mm length. Fits all common saddle rail types.
