The Summit 34.9 mm Bolt-On Seatpost Clamp is a straightforward replacement clamp for bicycle frames that require a 34.9 mm clamp diameter. Its bolt closure allows the rider or mechanic to set clamping tension with a tool, while the black finish keeps the installation understated.

Confirm the required frame clamp diameter before installation. The 34.9 mm measurement refers to the frame's external seat-tube clamping area, not the seatpost diameter.
