Chromag Seatpost Clamp

This clamp has a 35mm diameter. You must verify your frame's seat tube outer diameter or your current seatpost clamp size before purchasing, as this is not a universal fit.

The brass bushing creates a smoother interface between the lever and the clamp body. This reduces friction, allowing for a more consistent, powerful clamping force with less hand effort compared to standard metal-on-metal designs.

While the clamp is precision-machined, you should always consult your bike frame manufacturer's specifications regarding clamp compatibility. If your frame requires a specific torque setting or a non-quick-release style clamp to prevent damage, you should stick to those recommendations.

The lever features a long, rounded profile that distributes pressure across your palm, making it much more comfortable to open and close. This ergonomic shape is specifically designed to minimize hand fatigue, especially when you need to adjust your seat height frequently.

Yes, the clamp is hard-anodized, which provides a robust, corrosion-resistant layer. It is built to withstand exposure to the elements, though regular cleaning and a light application of grease on the cam surface will keep it operating smoothly over time.
