Featuring a carbon composite body and a durable stainless steel plate, these pedals offer a wide platform for enhanced stability and efficient pedaling. They use sealed cartridge bearings to reduce maintenance and improve durability. The pedals fit standard 9/16 inch pedal axles and pair well with Shimano SPD-SL cleats (not included). Adjustable spring tension allows riders to customize the clip-in and release feel, accommodating a range of rider preferences and skill levels. Weighing approximately 278 grams per pair, they strike a balance between durability and weight, suitable for enthusiasts and competitive road riders who want dependable performance without premium costs. These pedals share design elements with higher-end Shimano models but focus on solid function and long service life for road and triathlon use.
