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 tread.
Today’s version of the composite SRS® sole is found on the Spider. The SIDI SRS® sole allows SIDI to maximize both traction and durability. 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. It is toe spike compatible.
* To validate our warranty and prevent sole cracking, the SIDI Reinforcement Plate is required for use with dual retention-bar style MTB pedals (Crank Brothers®, Time® and Look®). The plate is not required for Shimano®-style pedals.
