Product Description

Fit and Performance

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 giving 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.

Available in two color schemes: High-polished Black with silver laser-etched graphics or Beyond Black anodized with black.

Note: torque for the seat rails is 7Nm.

Minimum insertion length is 90mm.

Seatposts Guide

What are seatposts?

The seatpost is the extendable metal rod that slots into your bike’s frame, with a clamp at the top to hold your saddle.

Who needs a seatpost?

Every bike has a seatpost, but a common reason for fitting a new one is to get a longer post for a leggy rider. Weight saving is another prime reason for upgrading.

What are the choices?

You need to pick the right seatpost width for your frame, but then you will have a choice of materials, from practical aluminium to weight-saving carbon. Mountain bikers can also opt for dropper posts, which are tremendously useful out on the trails.

What should I buy with them?

You might need a different seatpost clamp to go with your new seatpost and hold it firm in your frame.

Anything else?

Finding out which seatpost width you need can be a tricky business. With luck it will be stamped on the inside of your bike’s seat tube. It is measured down to tenths of millimetres, so eyeballing it with the tape measure won’t work.
