Lightweight CNC Seat Clamp with Hope’s Signature Finish
The Hope Seat Clamp is a proven and highly popular upgrade for modern mountain bikes, combining precise machining, reliable clamping force, and Hope’s signature anodised finish. Designed for everyday trail riding, enduro, and gravity use, it provides a secure connection between the frame and seatpost while remaining lightweight.
CNC machined from high-quality 2014 T6 aluminum, the clamp features a spherical bolt and nut system that ensures perfect alignment and consistent clamping pressure. It is also an excellent choice for bikes equipped with dropper seat posts, providing dependable holding power without unnecessary weight.
Available in seven anodised colors and multiple sizes, the Hope Seat Clamp offers a clean, custom look for almost any MTB setup.
Note: The seat clamp size refers to the diameter of your bike’s seat tube, not the seatpost diameter. Always check your frame manufacturer’s specifications or measure the seat tube directly with vernier calipers to confirm the correct size.
