SDG Tellis Cartridge V2

No, this cartridge is specifically engineered for the Tellis V2 series. It will not fit or function correctly in the original V1 model.

You should consider a replacement if you notice your seatpost is sagging under weight, returning sluggishly, or failing to hold its position at full extension. These are common signs that the internal hydraulic seal or pressure has degraded.

The kit includes the essential lock nut tool and bottom-out bumper, which covers the most difficult part of the service. You will still need standard shop tools, such as a strap wrench or vice, to disassemble the post housing.

If you are comfortable with basic bike maintenance and have the necessary tools, this is a straightforward service. SDG designed this kit to be accessible for home mechanics, but if you are unsure about disassembling your seatpost, a local shop can handle the installation quickly.

This specific cartridge is designed for 200mm travel posts. It is a direct replacement part, so it will maintain the original travel specifications of your V2 post.
