Micro-adjustability during a ride separates a secure fit from a distracting one. The Caliper Buckle from Sidi handles the instep closure on several of their carbon-soled road shoes, ratcheting down the anatomical strap in small increments so you can dial tension without stopping. When it's time to remove the shoe, a quick-release mechanism lets the strap pull completely free from the buckle rather than requiring you to click backward through every position.

This is the same buckle that ships as original equipment on the Ergo2 Carbon, Genius 6.6 Carbon, and Genius 5.5 Carbon models. If your existing buckle has cracked, worn out, or simply gone missing after one too many transitions, this direct replacement restores full function without compatibility concerns. The composite and metal construction handles the repetitive stress of daily clipping and unclipping, and the materials resist corrosion from sweat and road spray that can seize cheaper closure hardware over time.

Each pack contains two buckles and the mounting screws needed to install them, covering both shoes in your pair. The straps themselves are sold separately, which actually works in your favor if only the buckle has failed. No need to replace components that still have life in them. If you're running any of the compatible Sidi models and the buckle action has become sluggish, gritty, or unreliable, fresh hardware restores that crisp engagement you had when the shoes were new....
