OverLock™ Seatpost Clamp

A high-leverage seatpost clamp

Licensed from Syntace, this seat clamp is designed to maximize clamping force and durability while minimizing weight and lever force. Fanatical attention to the tiniest detail is a hallmark of Syntace engineering.

  • High leverage clamp design – A long lever, combined with zero distortion stainless steel bushing, and a 3D-machined clamp results in more force transferred to clamping the seatpost
  • Precision & CNC machined – Precision machining means a perfect fit for your Tern bicycle
  • Stainless bushing – Eliminates corrosion and wear for consistent reliable transfer of clamping force
  • Polished lever – Special polishing of the lever reduces friction for easier operation
  • Light weight – 57-grams light in 40.8 mm size
