Elite road racers demand reliable and precise shifting. The Shimano Dura-Ace R9100 front derailleur delivers with its super-lightweight yet durable design. It features a lighter and more intuitive shifting operation thanks to toggle link leverage construction. The cage design has been improved, eliminating the need for outer trim, allowing the rider to focus on racing. The lightweight nickel-plated forged alloy chain cage reduces weight and increases rigidity while resisting abrasion from the chain. The extra wide pivot link and optimized spring tension provide a rigid, flex-free shift while being smooth and light in action. The forged aluminum construction reduces weight without sacrificing durability, and the hard-wearing finish is expected of Dura-Ace. The derailleur also features integrated cable tension adjustment. It has a maximum capacity of 16 teeth, suitable for use with outer rings 50-55T. The weight is 69 g (braze-on).
