Product Information
Full details
The DMR Hinged Clamp (28.6mm) is an essential component for cyclists looking to customize their setup, specifically designed for those who need to add utility accessories like bottle cages or mudguards to frames lacking integrated mounting points. This robust accessory is perfect for riders performing frame upgrades or setting up a commuter bike for long-distance comfort, though users should note that most installations—such as adding a standard water bottle cage—require two individual clamps to ensure a secure, stable fit.

FAQs
Does this clamp come with mounting bolts for accessories?
The DMR Hinged Clamp provides the threaded interface, but you should use the bolts supplied with your specific accessory (e.g., the bolts that come with your bottle cage).
Can I use this on a carbon fiber frame?
It is generally not recommended to use metal clamps on carbon fiber, as the concentrated pressure can damage the frame structure. Always consult your frame manufacturer's guidelines.
Do I need two clamps for a bottle cage?
Yes, standard water bottle cages require two mounting points to remain stable, meaning you will need two DMR Hinged Clamps for that specific setup.
What is the weight of the clamp?
The clamp is designed to be lightweight, typically adding negligible mass to your overall bike setup.
Can this be used for other diameters?
No, this is specifically sized for 28.6mm tubing. Attempting to use it on larger tubes will prevent it from closing, and using it on smaller tubes will result in an insecure fit.
Troubleshooting
The clamp slips or rotates around the frame tube.
Clean the frame tube with isopropyl alcohol to remove grease. If slipping persists, apply a small piece of inner tube rubber between the clamp and the frame to increase friction.
The bolt is difficult to thread during installation.
Ensure the hinge is fully closed and the holes are perfectly aligned before attempting to thread the bolt. Do not force it, as this may strip the threads.
Pros and Cons
Pros
- Simple hinged design allows for quick installation and adjustment
- Provides mounting options for frames that lack dedicated bosses
- Lightweight yet durable enough for consistent daily use
- Consistent 28.6mm sizing ensures reliable compatibility with many classic bike frames
Cons
- Sold individually, requiring two units for most common accessory setups
- Not suitable for oversized carbon frame tubing
- Requires careful tightening to prevent rotation on the frame
Setup, Compatibility & Care
To install, open the hinged mechanism and position the clamp around the designated 28.6mm frame tube. Before tightening the bolt, ensure the clamp is at the desired height. If the clamp feels loose, verify that your frame tube is exactly 28.6mm in diameter; using this on a smaller diameter tube will cause slippage. Use a standard hex key to tighten the bolt securely, but avoid overtightening to prevent marring the frame paint. For care, periodically inspect the bolt to ensure it hasn't vibrated loose over time and wipe the area clean of grit or moisture after wet rides to prevent corrosion.
