SDG Tellis Dropper Seatpost

This specific model has a 34.9 mm diameter, so you must ensure your bike frame is designed for that seatpost size. It also requires a frame that supports internal cable routing.

The Tellis is known for its exceptionally light and smooth lever action. It uses a high-quality bearing system that requires very little thumb pressure, making it easy to actuate even during long rides.

Yes, it is engineered to function reliably in cold weather down to -20°C. The internal design is built to maintain consistent performance even when temperatures drop significantly.

The Tellis features an intelligent keyway system designed to minimize rotational play. While no mechanical dropper is completely devoid of movement, this model is widely regarded for its tight, stable feel.

Installation is straightforward, especially because the cable head attaches at the base of the post. This design eliminates the need to measure and cut the cable at the lever end, which simplifies the setup significantly.

It means you are not limited to fixed positions like 'up' or 'down.' You can stop the saddle at any point within its 150 mm of travel, allowing you to dial in the exact height you need for any specific trail section.
