The Spinetech buckle combines the regular fixed bridge buckle with a new design and geometry inspired by Spineflex technology. As on the Racing models, the Spinetech buckle features a constant traction closure point. This translates into a reduction in pressure points, an increased overlap between shell flaps, more comfort, and more precision.

The new, more ergonomic, patented patented Double Power arm makes the closure even more precise and efficient with a minimum effort.
