Spider SRS® is the pick of the litter for high-performance, high-mileage cross-country riders and cyclocross racers. An integrated rubber toe guard and replaceable tread give more durability, while the integrated instep traction pad provides extra grip during less-than-perfect cyclocross remounts. Better pedaling, easier pushing, faster on the run—this is the shoe that does it all.
Spider SRS Technomicro/Mesh features a Technomicro upper with cooling mesh panels for better ventilation (Spider SRS Technomicro provides the same terrific features with more weatherproofing).
SPIDER TECHNOMICRO/MESH TECHNICAL FEATURES
• Sole Replacement System® (SRS®)
In 1999, SIDI revolutionized mountain bike shoe design with the Sole Replacement System® (SRS), allowing mountain bikers to replace the most wear-heavy part of the shoe—the sole.
Today, versions of the SRS® sole are found on the Drako and the Spider. Since the tread is replaceable, SIDI can use an aggressive, softer durometer in the tread for increased traction in slippery conditions. Like most SIDI small parts, the SRS® tread panels and screws are available as spare parts.
The SRS® sole on the Spider models features a more generously sized polyurethane anti-slip insert beneath the instep, which helps during less-than-perfect cyclocross remounts, making it ideal for cyclocross racers. For 2013, the Spider SRS® sole is produced in a firmer durometer than previous years to increase tread life for cyclecross racers and MTBers in “push” situations.
• 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®).
• Adjustable Heel Security System® (HSS)
The Adjustable HSS®, introduced in 2006, reinforces the top of the heel cup and adjusts to securely close around the heel just above the calcaneus (heel bone), eliminating power-robbing heel lift during the pedal stroke.
Like most SIDI small parts, the Adjustable HSS® is replaceable, and also available as an aftermarket upgrade to 2007 thru 2009 SIDI models.
• 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.
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.
• 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.
