Shimano Dura-Ace Di2 2x12-Speed R9250 Rim Brake Groupset

The Shimano Dura-Ace Di2 2x12-speed R9250 rim brake groupset is for riders using rims with braking surfaces on road bikes who want wired electronic shifting with 2 chainrings and a 12-speed cassette. It includes wired ST-R9250 levers, front and rear BR-R9200 brakes, a braze-on FD-R9250 front derailleur and a CS-R9200 11-30T cassette.

The groupset does not include a crankset or bottom bracket: choose these components according to your frame's dimensions. The set includes a BT-DN300 battery, a 1500 mm EW-EC300 charging cable and a CN-M9100 chain with 126 links. Choose this version only if your frame and wheels use rim brakes, as this model is not for disc brakes.

Founded in 1921 in Sakai, Japan, by Shozaburo Shimano, Shimano is still based in the same city today. For cyclists, it makes drivetrains, brakes, wheels, pedals and cycling shoes. Its history in bicycle components began with the production of freewheels in 1922.
