Tidy seat clamp that tidies dropper cables too

It’s nice to come across a product that is reasonably priced, lightweight, and does exactly what it’s meant to.  Promax’s DP-1 seat collar is nothing revolutionary, but useful all the same.  A seat clamp with an easily positioned dropper post cable guide, the DP-1 does two things: holds seatposts and guides flappy dropper post cables.

Simple solution for common problem

The DP-1 performs both functions without complaint.  The seat clamp’s angled slot and non-binding barrel are kind to aluminium and carbon frames. The nylon cable guide, held in place by a pair of tiny screws, can be positioned as needed in slots on either side of the clamp.  Those tiny screws are a bit fiddly and can crack the nylon if over-tightened, but once set even a cracked guide has guided our dropper cable without binding or moving for the better part of a year.

The price (£10/$15) and weight (25g) are reasonable and black, gold, red, and blue annodised colours are available.  If a Stealth-style internally-routed post is purchased, the guide can be removed altogether.  35mm diameter only, to suit most dropper-friendly frames.

  1. Anyone selling them over here yet?

  2. One of these came free with my new Transition Bandit frame, cheers to Surfsales!

  3. Chris,

    We’ve reached out to Fisher – the official distributors – but haven’t had confirmation that they’ll bring this piece in. It’d be a shame if not, though.


  4. A QR one on the way?
    I often drop the dropper for more drop for ‘testing’ sections, 150mm isn’t always enough

  5. Tidy but 2 cable ties does exactly the same job on the QR of your choice…

  6. my reverb came free with a little guide, works well 2 years later
