The Shimano Ultegra FD-R8150 is the 12-speed Di2 front derailleur for Ultegra R8100-series electronic groupsets, delivering precise, low-effort front shifts at the push of a button — even under load on steep climbs.

• Electronic Di2 actuation for instant, consistent front shifts with zero cable fatigue
• 12-speed compatibility, designed for Shimano Ultegra R8150 and Dura-Ace R9250 Di2 systems
• Micro-adjust positioning reduces front derailleur setup time and eliminates trim fussiness
• Compact, lightweight motor unit integrates cleanly with the frame
• Synchronised shifting capability when paired with a compatible Di2 rear derailleur

Shimano Ultegra Di2 electronics have always offered a performance level that matches the brand's flagship Dura-Ace, and the FD-R8150 is no exception. The derailleur uses a small servo motor to move the cage with precision and speed that mechanical systems cannot match. Automatic trim adjustment means the cage automatically positions itself to eliminate chain rub without any input from the rider — particularly useful when cross-chaining.

Designed exclusively for use with Shimano Ultegra R8150 and Dura-Ace R9250 Di2 12-speed electronic groupsets. Requires a compatible Di2 junction box, battery, and wiring. Not compatible with 11-speed Di2 (R8070/R9150 era) or any mechanical groupset.
