The MTB SRS Carbon-Ground Sole consists of replaceable tread blocks in the toe and heel attached to a medium-modulus carbon sole, plus the innovative Replaceable MTB Plate, designed to prevent sole damage from pedal contact. Most Dual-Retention Bar type MTB Pedals (such as Crankbrothers and LOOK) recommend using a reinforcement plate between the cleat and the shoe in order to prevent cracking or denting the sole. The MTB Plate can be replaced in case of damage from the pedal system, so adding the weight of an aftermarket reinforcement plate is optional. The Ground SRS treads and MTB Plate are easily removable and replaceable. The MTB SRS Carbon-Ground Sole is toe-spike compatible Microfibre Techpro: Microfibre Techpro is a microfiber PU Made in Italy. It is considered a highly technological and innovative eco-friendly leather suitable for technical and sports products which require high performance levels. Microfibre Techpro incorporates features of resistance, stability, lightness, water-repellent properties and eco-friendliness. Microfibre Techpro has a Hydro and anti-mould treatment, which eliminates the onset of moulds and bacteria. Microfibre Techpro is Oeko-Tex certified, does not contain harmful substances and respects law restrictions Tecno-3 Push: This Tecno-3 Push system fits along the entire length of the shoe and adapts the upper to the shape of the foot for a customised fit. Sidi’s famously reliable and replaceable closures are improved by an all new proprietary Sidi wire material that is completely non-binding for intuitive and effortless on-the-fly adjustments. Like most Sidi small parts, the Tecno-3 Push buckle is serviceable and replaceable. It can be adjusted while riding thanks to an innovative button which can be pushed to lift the buckle and facilitate adjustment Sidi Heel Cup: Reinforced cup that stabilises and supports the heel. Anatomically shaped plastic reduces heel slip and provides increased power transfer. Provides additional foot protection in the event of a crash High Security Velcro: High Security Velcro straps with integrated locking polymer teeth that engage onto each other when the strap is closed. This feature makes the closure more secure and the strap becomes unmoveable Soft Instep 3 System: The Soft Instep 3 System is a wide, anatomically curved strap combined with a soft, thermoformed EVA pad that distributes pressure evenly over the instep area. The Soft Instep 3 System is adjustable from both sides, to perfectly centre the EVA pad over a high or low instep. The system eliminates the need for the High Instep Extender Reflex Adjustable Heel Retention Device: The Reflex Adjustable Heel Retention Device reinforces the top of the heel cup and improves the fit by closing the back of the shoe securely around the rider’s heel. The heel retention device tightens the top of the heel cup so that the heel doesn’t slide out during steep climbs or sprints. Each side of the heel can be adjusted independently, for a perfect fit. For a custom adjustment turn the screw towards the “+” sign to tighten the heel retention device and towards the “-” sign to open it. Lightweight, easy to use, and replaceable. For additional security while pedalling, the new adjustable heel device is provided with reflex inserts for more visibility in dark conditions Mega Last: 4mm wider across the ball of the foot, more volume, a high instep and wider heel cup, Mega Lasts are ideal for a wider fit: EE to EEE width Buy Sidi Footwear from Chain Reaction Cycles, the World’s Largest Online Bike Store.
