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.
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.
