Sidi's Caliper Buckles replace any Sidi ratchet system to get you back on the road. With precise tightening and simple loosening mechanisms, the Caliper Buckles keep your shoes secure. Retrofitting them onto older Sidis requires replacing the straps with Caliper Straps (sold separately).
Fits SP Carbon, Vent Carbon, Eleven Carbon/Composite, Millenium 4, Carbon Composite, and Carbon Lite soles
