Another highlight is its etched Zipp logo finishing, which gives it a sleek appearance to complement your ride.

This versatile seatpost is suitable for both road cycling and gravel adventure riding, thanks to its special shock-absorbing properties and increased comfort. Zipp has also put this model through a strict mountain bike (MTB) strength test, so you can enjoy offroad durability and support on your road or gravel bike. Benefitting from a unidirectional (UD) carbon construction, it provides the best balance of stiffness, strength and low weight performance as you conquer every mile of road. Another highlight is its AL7075 aluminium head and robust steel hardware, which ensures a tight and secure hold to your saddle rails whatever the terrain conditions. Adjustable Carbon Seatpost The carbon Service Course SL seatpost is specifically tuned to be more shock-absorbing than the “comfort” seatposts on the market, while still passing Zipp's strict internal MTB strength test. Flex engineered into the lightweight carbon tube keeps the rider comfortable over any terrain. Better fit means better performance, and if your saddle is out of position, you’ll waste energy with every pedal stroke. The secure, two-bolt clamp makes for easy micro-adjustments of saddle position, and the head has been redesigned for maximum bolt head accessibility. With 0mm and 20mm setback options to choose from, it’s possible for nearly any rider to achieve the perfect fit, and the clamp works with all saddle rail types.

Shims are available in Aluminum and Thermo Plastic, despite the latter being a lighter solution its material characteristics limit the thickness of the ID - OD measurements. Aluminum is used to achieve the thinnest shims as it is a more robust material. Rolled Aluminum shim - the very thinnest shims are rolled from sheet metal. 25.4mm shims need to be so thin as they are etched down in acid to the correct tolerance and are too thin to anodise (show as silver). Machined Aluminum shim - machined to very high tolerances from 6082 T6 Aluminum and then black anodised to protect from corrosion. Machined Plastic shim - larger size shims are machined to very high tolerances from "filled" engineering thermoplastic UPVC. This keeps the weight down, as the shims get thicker.
