Custom Fit Carbon Fiber sole with a replaceable heel strike pad. Available in a 3-hole cleat pattern.

Klite Kangaroo leather & Carbitex OmniFlex Carbon Fiber Stabilizer Support panels help keep the foot stabilized, control stretch and allow for increased power transfer. Lined with Perforated Kangaroo leather for great fit & feel. Moldable carbon heel.

BOA® Fit System Li2 dials. The Li2 dial is the most advanced platform in cycling, offering a precise, micro-adjustable fit in both directions and designed to resist abrasion.
