FAQs
How do I know which size to buy?
You must measure the external diameter of your frame's seat tube, not the seat post diameter.
Can I swap this to a bolt-on clamp?
Yes, the universal collar is designed to be easily swapped between bolt and quick-release configurations.
Is this clamp compatible with carbon seat posts?
Yes, but be careful not to overtighten. Always use carbon assembly paste to ensure a secure hold at lower clamping forces.
What is the material used?
The clamp is precision machined from high-grade T6 billet aluminum.
Does it come in different colors?
Hope typically offers their components in a variety of anodized colors, though availability varies by specific model.
Troubleshooting
Seat post slips after tightening
Clean the seat tube and post of all grease or debris, then increase the tension by tightening the adjuster nut slightly while the lever is open.
Lever is difficult to close
Back off the tension nut until the lever closes with firm but manageable pressure, or clean the cam pivot point.
Pros and Cons
Pros
- High-quality, durable T6 aluminum construction
- Easy, tool-free saddle height adjustment
- Versatile collar allows for conversion between bolt and QR
- Available in a wide range of frame sizes
- Excellent build quality consistent with Hope components
Cons
- Requires precise measurement of seat tube diameter before purchase
- Quick release levers are more susceptible to theft if not properly secured
- Heavier than traditional lightweight titanium or minimalist bolt-on clamps
Setup, Compatibility & Care
Before installation, verify your frame's seat tube outer diameter using a digital caliper. Do not attempt to force a 31.8mm clamp onto a larger frame, as this will damage the component and potentially the frame.
- Clean the seat tube and the inside of the clamp to ensure a grit-free interface.
- Slide the clamp onto the seat tube, ensuring it is seated below the cut-out in the frame.
- Adjust the tension nut on the opposite side of the lever while the lever is in the open position.
- Close the lever to test the hold; it should feel firm and secure without requiring excessive force.
For care, wipe the clamp down after wet rides and apply a tiny drop of light lubricant to the cam pivot occasionally to ensure smooth operation.
