Promax DP-1 Dropper Post Seat Clamp 34.9mm
The Promax DP-1 Dropper Seat Post Clamp is the first seatpost clamp to offer a cable/hydraulic line guide... built right into the clamp! Make your dropper post cable routing look clean and professional with the DP-1.
The first one wouldn't hold at maximum torque. The second one broke at 5NM and was replaced by Promax The third one stretched before reaching maximum torque and I replaced it with a Thomson. No more problems. For my setup, the line guide isn't necessary.
