Shimano Ultegra Di2 R8050 2×11-speed Direct Mount Groupset- Rim Brakes for Quick Assembly
The Shimano Ultegra R8050 Di2 2×11-speed Direct Mount Groupset is delivered with a direct mounting rim brake set. Front brakes are attached directly to the fork, while rear brakes are attached directly to the seatstays, creating an aerodynamically superior construction. The remaining components are comparable to those supplied in other electronic racing bike groupsets: a crankset with two chainrings (34-50 Z), an 11-speed cassette (11-28, 11-30 or 11-32 Z), a Quick-Link chain and of course a pair of Di2 shift/brake levers (STI), a Di2 front derailleur, Di2 rear derailleur, battery, Junction A (internal or external), Junction B and charger. Operating under the motto ” rider tuned,” Shimano introduces with the R8050 a professionally-proven Ultegra Di2 groupset, striving to meet every rider’s needs.
