Promax DP-1 Dropper Seat Post Clamp

Promax DP-1 Seat Post Clamp

The very first multi-tasking seatclamp has arrived! Cold forged and CNC machined from resilient 6061-T6 aluminum alloy, the DP-1 clamp is designed to be used with a remote dropper seatpost. Keep your cable secure and protected as this clamp directs and guides between the lever and seatpost. The DP-1 clamp is refined and lightweight, weighing in at only 20 grams to provide the unscathed routing a dropper post requires. The laser etched graphics and stainless steel hardware give the DP-1 clamp good looks to go along with its intelligence. The perfect combination!

  • Designed to work in conjunction with a remote dropper seatpost
  • Cold forged and CNC machined from 6061-T6 aluminum alloy for durability and dependability
  • Claimed weight: 20 grams
  • 34.9mm
  • Laser-etched graphics and stainless steel hardware
  • Meets or exceeds ENM standards

Good
My dropper's cable comes out from the stationary base of the post and so the cable is static. This clamp is clearly more suited for dropper's where the cable is attached to the top of the post. Use your dropper post's manual for determining max torque for the clamp.

Great solution
Must have for a frame/post where internal routing through the seat tube is not an option. I use it with my Stumpjumper FSR and Specialized Command Post.

I don't think this would work or even be necessary with a KS LEV. This is for posts where the cable runs up under the seat.

PROS: Lightweight, Easy To Install, Attractive Design

Can't believe there aren't more of them!
There's not a lot to say really: if you have a dropper post with the cable attached to the telescopic part of the seat post (and therefore cable movement during actuation), then 2 things should be clear to you:
1. Be thankful you didn't jump onboard the stealth and fixed cable position posts trend so soon ... what a stuff up those posts have been!
2. You should most definitely have this clamp. It's a no brainer .... assuming like me both your bikes have the one size clamp offered.

CONS: Limited Compatibility

Use the correct torque
It does a good job of keeping the cable where it is supposed to be while letting it move up and down, but I already broke mine. While on a ride I decided I needed to move my seat forward and post up just a little, and with my tiny multi tool I torqued it enough to break the clamp. I cant really blame the clamp since the max torque is printed right on it, but it is definitely worth knowing that it isnt a good idea to attempt an adjustment on the trail without the proper tools.
I have another one on a different bike that I set up right the first time and Ive had no problems with it.

Great product I've bought for two of my bikes
It's a great product but only thing I noticed is the cable holder will break if tighten to much other than that works fine

XLNT for full length hydraulic hose
Purchased this clamp as an upgrade to the stock ziplock clamp that comes with the Rockshox Reverb. The guide can be located wherever you choose, and keeps the hose from going places you don't want it to. Well built, cool design and colors. Use it on every bike with a Reverb or similar hose setup. No regrets, No worries.

CONS: NONE

Excellent - does it's job without issue
Didn't need to adjust the cable router for the dropper post but nice that it's there if I see rubbing or it starts hitting my leg. I was surprised that it has managed with the recommended torque value; usually these need a little extra. nice finish and the fact that I haven't even thought about it means it's doing its job flawlessly.
