With the fastest, most accurate shifting on the market, the new 12-speed ULTEGRA R8150 rear derailleur is more versatile than ever thanks to a single cage length option compatible with 11-28, 11-30, and 11-34 cassettes.
Shimano Ultegra BR-R8100 Brake Caliper
The Shimano Ultegra BR-R8100 side-pull brake impresses with a clear contact feeling and a well-balanced ratio between braking power, stiffness and low weight.
The brake caliper owes this to a sophisticated Dual Pivot construction as well as SLR-EV technology. Despite increased 28C tyre clearance, the rim brake features a decidedly slim design.

Shimano EW-EC300 Charging Cable - 12 Speed
The Shimano EW-EC300 charging cable has been specially designed for Shimano Di2 12-speed road bike groupsets and is compatible with the components of the current Dura Ace R9200/R9250 and Ultegra R8100/R8150 series.
The charging process of the electronic Di2 system is carried out starting from the rear derailleur which features a corresponding connection. However, the charging cable can also be used for compatible Powermeter cranks. In each case, it draws power via a USB-A port.
Shimano BT-DN300 Internal Battery - 12 Speed
Thanks to its compact dimensions, the flat Shimano BT-DN300 battery can be integrated inconspicuously into the seatpost or frame. Not only in terms of dimensions, it is similar to its predecessor BT-DN110, but also concerning waterproofness, it is in no way inferior.
The lithium-ion battery features three SD300 ports for the connection to front and rear derailleur. The third connector is used in the case of a fully cabled Di2 groupset.
In-house tests with the components of the current Dura Ace R9200/R9250 and Ultegra R8100/R8150 12-speed series have shown that the battery provides a powerful and stable power supply for the powerful actuators of the rear and front derailleur over a range of 1000 km on average.
