Shimano Ultegra Di2 R8050 11 Speed Front Derailleur

New ULTEGRA R8000 series is "pro-proven" as it is a direct trickle down from DURA-ACE groupset. As road bike component, the stress-free operation is one of the most important feature to lead all day riding comfort with braking and shifting.

• Quick and smooth front shifting under high pedaling torque
• Redesigned to fit a wider gear pitch without sacrificing shifting performance

• Programmed chainguide control
• SHIMANO SYNCHRONIZED SHIFT
• Shorter rear-center length (410 mm) with 135 mm O.L.D.
• System communication with rear derailleur, combined with programmed chainguide control means minimal chance of chain drop
