This kit is designed to secure the seatposts in place and protect it from theft.
This aftermarket kit is a replacement product for all non-secure clamps out there; the common Quick release concept, and also screw based ones.
It is compatible with almost all standard tube sizes; 28.6, 30, 31.8 and 35 mm (Note this is the outer diameter of the seat tube, not the seat post). With less than 5 minutes of installation, it will guarantee seatpost protection forever.
