Updated with a new look and lighter materials, the Shimano 105 PD-5800 Road Pedals finally get a carbon body, reducing weight by a whopping 40g! They even feature trickled-down technology from Dura-Ace and Ultegra for affordable, race-level performance. Carbon composite body offers low weight, rigidity and efficient power transfer. Stainless steel cover protects the carbon from abrasion and the wide contact area stabilizes the foot. There's also a low maintenance compact axle-bearing unit, fast and easy engagement, adjustable release tension and a new bearing assembly for longer life.
