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.

  • Ultralight Design: Weighs only 81 grams per pair, making it the lightest clipless pedal system on the market.
  • Smooth Pedal Action: Features two large stainless steel bearings in each pedal, ensuring low friction and ultra-smooth performance.
  • Standard Three-Bolt Cleat Compatibility: Retains the universal three-bolt pattern, compatible with most road cycling shoes.
  • Fixed-Position Design: Provides a solid, locked-in feeling with no float for maximum power transfer and efficiency.
  • Backwards-Compatible Cleats: New cleats are compatible with legacy Mercury pedals, and legacy cleats work with Mercury SL.
  • Compatible with all road shoes featuring the three-bolt pattern, ensuring universal fit.
  • Backwards-compatible with all previous Mercury cleats.

Lightest Pedal System Ever Made

At the top of the TriRig SL line sits Mercury SL: the long-awaited followup to our cult-classic weight weenie pedals. Mercury SL retains the ultraminimal design of its predecessor, but improves upon it in every way.

Lightest Pedal Body Ever Made

We managed to fit two large stainless steel bearings into the pedal body, larger even than most bearings that are in your current pedal. These reduce friction and ensure ultra-smooth pedal action. Yet we managed this improvement without a single added gram of weight. The pair of pedals comes in at 71 grams complete, less than ONE THIRD the weight of a set of top-shelf competitor pedals, and the lightest three-bolt cleat system ever made.

Lightest Cleats Ever Made

We don't make any sacrifices to cleat design to accomplish its lightweight design: Mercury SL retains the standard three-bolt pattern of every road shoe on the market, with improved range of adjustment.
