Tern Seatpost Clamps QR with Acorn Nut

Tern Seatpost Clamp with Acorn Nut / Quick Release. It is commonly designed for the lower or upper telescopic tubes on heavy-duty cargo and folding models like the Tern GSD, HSD, Vektron, and BYB.

The acorn nut mechanism is designed to prevent overtightening while providing secure clamping force for heavy cargo loads. Because Tern utilizes multi-stage telescopic posts, you must match the exact tube position and frame diameter you need to replace.
