Mercury SL Pedal System

Mercury SL Pedal System: The Ultimate in Lightweight Performance

The Mercury SL Pedal System stands out as one of the lightest clipless pedals on the market, making it an ideal choice for cyclists focused on shedding grams without sacrificing performance. With an ultraminimal design that retains the sleek profile of its predecessor, the Mercury SL improves upon every aspect of the pedal’s performance.

The Mercury SL is equipped with two large stainless steel bearings in the pedal body, reducing friction for an ultra-smooth pedal action. These bearings are larger than those found in most competitor pedals and provide enhanced durability and performance, all while maintaining the Mercury SL's industry-leading weight of just 81 grams per pair. That’s less than one-third the weight of many top-tier pedals, making this the lightest three-bolt cleat system ever produced.

Despite its ultralight design, the Mercury SL retains the standard three-bolt pattern compatible with nearly every road cycling shoe on the market, offering a wide range of adjustment for an optimized fit. Even better, the new cleats are backwards-compatible with legacy Mercury pedals, and legacy cleats work seamlessly with the Mercury SL.

For riders who value a locked-in feel, the Mercury SL continues to offer a fixed-position design with no float and is the top choice for cyclists who demand lightweight performance without compromise.
