2020 Bontrager Eyeleted QR Seatpost Clamp

Retrofit any bike for a rear rack with the Bontrager Eyeleted Quick Release Seatpost Clamp — a clever, practical upgrade for frames that don't have built-in rack eyelets. Threaded eyelets are built directly into the clamp body, providing secure rear rack mounting points on non-eyeleted or smaller frames without any permanent modifications.

The quick-release lever with rubber grip makes saddle height adjustments fast and tool-free, while the eyeleted design opens up rack compatibility on bikes that would otherwise be limited to unloaded riding. Available in three sizes to fit most common seat tube diameters.

Available in Black. Sizes: 31.9mm, 35mm & 36.4mm.
