SDG Tellis V2 Dropper Seatpost The next generation of reliability The original SDG Tellis Dropper Seatpost has long been known by riders to be one of the most reliable dropper posts on the market. This updated SDG Tellis V2 Dropper expands on and elevates what was already one of the best droppers available. The new V2 makes it easier than ever to get the perfect fit on any bike, with a new 3D forged seat clamp with a 3D forged head and a lower stack height, a new low-profile actuator for less wasted space, and a new easy-to-use travel adjustment shims to quickly reduce the travel of your V2 Tellis. The V2 Tellis also features a new polycarbonate keyway system with lower copper shims, for less head play and a more robust design while maintaining smooth actuation. An even more durable design, more adjustment, and improved fitment, that's how you improve on a classic.
