Sunlite QR Seat Clamp – 31.8mm – Black

The Sunlite QR Seat Clamp is a quick-release seatpost clamp designed for bikes that need fast, tool-free saddle height adjustment. It’s a straightforward, reliable option for commuters, shared bikes, and riders who frequently adjust fit.

CNC-finished alloy construction keeps it lightweight while providing enough clamping force for everyday riding.
