While I think the seat dropper is a good value, I was really disappointed in the lack of installation instructions. I understand there is a web link to installation information, but those are so lacking in any detail, it's really bad! If you've never installed one of these before, check the instructions provided with each one. Tranzx provided no guidance on cable routing. They didn't provide much detail on how the cables parts are assembled, and nothing on how to route the cable into the lever on the handlebars.

I got it installed and all seems working, but it could have been a lot better with more detailed instructions and tips.
