This GRX 825 Di2 12-Speed Kit, curated by Excel Sports, bundles the most advanced Shimano GRX and Di2 components to date, allowing riders to build the ultimate 12-speed drop bar gravel bike. Covering drivetrain and braking needs, the kit includes all necessary items, excluding those dependent on rider preference: a Shimano Crankset, 24mm Shimano compatible bottom bracket tailored to your frame, and disc brake rotors. Also provided is a Shimano 11-36T 12-speed road bike cassette. Di2-specific included additions comprise of an internal seatpost battery (BT-DN300) and a charging transformer with USB charging cable (EW-EC300). However, you'll still be required to purchase Shimano SD300 Di2 e-Tube wires and a Junction A type connection, with the IEWRS910 handlebar end type (Excel# 117254) being a popular choice. For further assistance regarding wiring specifics for your frame and handlebar setup, feel free to reach out to us at 800.627.6664 during business hours.
