SDG Components Tellis Upper Tube

No, this specific upper tube is designed exclusively for the Tellis Dropper Post line. You should verify your specific post model and diameter before purchasing to ensure a proper fit.

No, this is strictly the replacement upper tube assembly. It does not include the internal hydraulic cartridge, seals, or bushings, which are sold separately.

No, this tube is specific to the 170mm travel version of the Tellis post. Replacing the upper tube with a different length version will not change your post's travel, as that is determined by the internal cartridge.

You should consider a replacement if you notice deep scratches, scoring, or gouges on the stanchion surface that cause air leaks or prevent the post from moving smoothly. Minor cosmetic scuffs are usually fine, but structural damage that compromises the seal interface requires a swap.

It is a moderate repair that requires basic bike maintenance skills and specific tools to disassemble the post. If you are comfortable performing a standard service on your dropper post, you should be able to handle this, but consult the official SDG service manual first.
