The GP-M6250 is Shimano's boxed Deore Di2 drivetrain kit: everything you need to go wireless in one part number. Inside are the RD-M6250-SGS wireless rear derailleur, the BT-DN320 battery that lives inside it, the EC-DN100 USB-C charger and the SW-M6250 right-hand shift switch. Add a 12-speed cassette, chain and crank and the bike shifts electronically.

Highlights

• No wires, no frame ports — the derailleur carries its own battery and talks to the switch wirelessly
• Shifts under load — HYPERGLIDE+ on the 10-51T cassette, with the SHADOW ES clutch keeping the chain quiet
• Charge in place — the EC-DN100 plugs into the derailleur by USB-C; the switch runs on a coin cell
• Two switch mounts — band clamp for any bar, or I-SPEC EV to bolt onto a compatible Shimano brake lever
