The Shimano 105 FD-5801-B Front Derailleur is engineered for precision front shifting on 2×11-speed road bike setups. Derived from Shimano’s race-level technology, this updated 105 model uses the same refined actuation and stability found in Ultegra and Dura-Ace derailleurs.

The FD-5801-B features a wide-link design for improved rigidity and smoother shifting under load, while the integrated cable tension adjustment simplifies fine-tuning. Compatible with compact (50/34T) and standard (53/39T) chainring combinations, it delivers consistent performance across all 11-speed road drivetrains.

This is the band-on (clamp) version, suitable for frames without a braze-on mount, ensuring versatility across a wide range of road bikes.
