Secrets of the Pros: Many of SIDI’s sponsored pros specifically request the SIDI Eleven Carbon/Composite sole because of its perfect balance of comfort, light weight and power transfer—it’s slightly less stiff, for more comfort on long days without sacrificing ultimate power. And it’s the foundation for the NEW FIVE, pairing the Eleven sole with SIDI’s beloved upper technology: Caliper Buckle two-way ratchet closure, SIDI’s no-slip High Security Velcro® straps and, above all, SIDI’s trademark fit, and the comfort that comes with it—extending from perfectly formed toe box to SIDI heel cup.
FIVE CARBON AND FIVE CARBON WOMEN'S TECHNICAL FEATURES
• Eleven Carbon/Composite Sole®
The Eleven Carbon/Composite Sole® is engineered for high-performance, high-mileage cyclists, with stiffness for power transfer and some controlled flex in the toe area that biomechanically relieves stress in the plantar tendon. This makes it ideal for triathlon as it helps promote circulation and isn’t as punishing on the foot, leaving you more for the run.
The Eleven Carbon/Composite Sole® is extremely stiff. In SIDI’s rigidity test, in which a 50 kg (Eleven0 lb) weight is suspended from one end of the sole, it deflected only 2.4 mm—20% stiffer than the previous Carbon Composite sole’s 3 mm deflection.
The Eleven Carbon/Composite Sole® is constructed from layered 3k weave carbon fiber and injected carbon fiber in a matrix of Nylon 12, a mechanically stable material that is completely non-absorbent to water, so it won’t change rigidity from exposure to heat, humidity or from aging. It is an exceptionally light, stiff, durable sole.
An anti-slip insert in the toe and replaceable polyurethane heel pad help you navigate through transitions.
The Carbon/Composite Sole® uses a standard 3-hole drilling pattern for compatibility with the best pedal systems available, and includes a printed 10 mm lateral and fore/aft cleat alignment scale on the sole as well as the Look Memory Eyelet® for easy cleat alignment and replacement.
• Soft Instep Closure System®
The Soft Instep Closure System® is a wide, anatomically curved strap combined with a soft, thermo-formed EVA pad that distributes pressure evenly over the instep area.
The Soft Instep Closure System® is adjustable from both sides, to perfectly center the EVA pad over a high or low instep. Excess strap on the crank arm (inside) side of the shoe may be trimmed after adjustment. Like most SIDI small parts, the Soft Instep Closure System® is replaceable.
• Caliper Buckle
By 1988, clipless road pedals had become the norm, and this presented a new problem—shoe closures were put under tremendous strain, as a pedal stroke’s upward pull had to be entirely absorbed by the shoe without the additional support of a toe strap.
Dino Signori’s solution was as revolutionary as it was genius: In 1989, he introduced the first ratcheting buckle closure for cycling shoes, combining the robust holding power and on-the-fly adjustability of toe straps with the strength to withstand the powerful, repetitive pedal stroke of professional racers. It was the SIDI Micro Lock, the first micro-ratcheting buckle.
The current Caliper Buckle is the latest incarnation of SIDI’s famed ratcheting shoe closure. It ratchets in both directions, allowing for precise, incremental tightening and loosening of the closure, for easy on-the-fly microadjustment. Pulling upward on the lower lever tightens the strap, click by click; pressing down on the upper lever loosens it a step at a time; an outward pull on both side levers completely releases the buckle.
Caliper buckles may be retrofitted to older SIDIs, as long as the ratcheting strap is also replaced by the matching Caliper Strap (which fits older versions of the Soft Instep Closure System®).
• High Security Velcro®
In 2002 SIDI introduced High Security Velcro® (globally patented), with interlocking polymer teeth that engage when the strap is closed to provide a more secure, slip-free closure that dramatically increases the useful life of the Velcro® strap. Today High Security Velcro® remains an exclusive feature of SIDI cycling shoes.
• Sidi Heel Cup
The SIDI Heel Cup is an external, reinforced cup that stabilizes and supports the heel, with an anatomically shaped plastic design holds its form and doesn’t break down over time, helping reduce heel slip and increase power transfer.
Technomicro is a composite microfiber material created from strands that are so fine that each one is less than one thousandth the thickness of silk. These fibers act like natural leather skin, but with the advantage of better strength, softer texture and lighter weight. Technomicro is also water-repellent, quick-drying, breathable and permeable to water vapor, making it an ideal material for shoe uppers. It is abrasion- and mildew-resistant, easier to clean than leather and resists stretching and deterioration from atmospheric agents.
