Box one quick release seat clamp

Box One Quick Release Saddle Clamps are cold forged and CNC machined from 6061-T6 aluminum alloy. A quick-release lever makes adjusting the height of your saddle quick and easy. Weighing just 28 grams / 1 ounce for size 31.8, it is as light as it is durable.

The quick release lever head and collar face are subjected to a proprietary "zero friction" surface treatment that ensures smooth lever action for the entire life of the collar without the need for a bushing.

Available in size 31.8 with red, blue, silver and black anodized collars with black levers and gold pivots, laser etched graphics and titanium parts.
