Full Freedom of Movement at the Touch of a Button.

The SDG Postman Vario dropper seatpost in 31.6 mm with 170 mm travel is perfect for modern trail and enduro bikes. With one flick of the wrist, you can move your saddle out of the way, giving you more space for steep descents, corners, and technical sections – ideal for active riders who like to "work with" the terrain.

The Postman is based on the proven SDG Tellis platform and features an internally routed, mechanical actuation with a sealed cartridge. This ensures a defined pressure point at the remote lever and reliable function – even in bad weather. The robust aluminum construction is designed for tough MTB daily use and comes in a discreet, matte black finish.

As a YT OEM version, the seatpost comes with a remote lever with SRAM MMX mount. This allows the lever to be attached directly to compatible SRAM brake levers with a MatchMaker-X interface – a clean cockpit, fewer clamps. For other brake/shifter combinations, a separate handlebar clamp is required (not included).

Highlights:

• 170 mm stepless travel: plenty of freedom of movement for steep trails and technical descents.
• 31.6 mm diameter & 480 mm length: suitable for many modern MTB frames with internal cable routing.
• Internal cable routing: tidy frame design, protects the cable from dirt and moisture.
• Mechanical actuation: reliable, easy-to-operate dropper technology with a proven cartridge.
• 2-bolt clamp head: fine saddle angle adjustment and secure hold for common 7 x 7 mm saddle rails.
• YT OEM Version: factory-installed on YT bikes – developed for tough trail and enduro use.
• Remote with SRAM MMX interface: direct mounting to compatible SRAM brake levers, for a particularly clean cockpit.
