This new retention system features two Tecno-3 Push systems. There are two Techno buckle dials. The lower Tecno 3 is located on the center of the tongue and controls the lower and mid foot tension via four anchor points, while the upper Tecno just controls the two opposing upper anchors, so you can isolate the two levels of retention. This upper system is not centered, but the Push dial itself sits on the outside, and pulls the centering SIS 4 system across the top of the foot. Sidi believes that this combination, along, with the cut and shape of the upper, creates a more flexible closure on the both the instep and outer portions of the shoe- but still uses a standard tongue, which many dual dial systems do not. The Tecno buckles themselves are easy to use, and employ monofilament wires that don't stretch or rust. Due to the integrated nature of the system, the assemblies have fewer parts, but as with many other high-end shoes, the Double Tecno-3 Push System can be replaced if you have accident or damage part of the system. The Push feature allows for quick release of the adjustment lever, which them lock back down when done to maintain security. The system as a whole offers tremendous fit and comfort, as well as minute adjustability, ease of use, and long term viability.

The final area that rounds out the upper is the combination of the new Sidi Heel Cup and the Adjustable Heel Retention Device. Many riders love the hold and support of the excellent heel cup, but for those with more specific fit and retention requirements at the upper back of the shoe along the Achilles tendon, a screw controls the adjustable two-piece retention device, either drawing it in for narrow shapes, or opening up for wider shapes. This is pure customization and and pure Sidi, who have built such long standing relationships within professional riders that the most nit-picky needs of cyclists are not only identified, but taken care of, and what the same differentials that pro's have on their feet and ankles are found in the general population as well.

Designed with a 3-Bolt cleat pattern, the Wire 2 Carbon Road Shoe is optimal for Shimano SPD-SL and Look KEO cleat systems. Time I-clic X-Pro/Xpresso cleats generally sit a little flatter so on larger sizes (44 and up), they generally will work fine, but smaller sizes force too much curve on the cleat and may compromise fitment with the pedal. Speedplay pedal users can generally use the 3 to 4 bolt adapter plate and shim system for a proper fit. Sidi does offer the Wire 2 Carbon Road in a Speedplay direct 4-Bolt sole option in the Black colorway, but it has limited availability. If you contact us, we can look into availability for you.
