Description
This GRX 815 Di2 11-Speed Kit is an Excel Sports package of several specific GRX and Di2 items required to build an e-Tube wired 2x11 drop bar bike. Drivetrain and braking-wise, this package has everything you need except items selected by rider need/preference: a crankset, 24mm Shimano compatible bottom bracket, which will be specific to your frame, and disc brake rotors. We are offering a Shimano 11-34T 11-speed road bike cassette. For Di2-specific items we are including the internal seatpost battery, the charging transformer / charging cable w/ USB. You will still need all necessary Shimano SD50 Di2 e-Tube wires, and a Junction A type connection (most people opt for the IEWRS910 handlebar end type; Excel# 117254). Please feel free to call us at 800.627.6664 during business hours to discuss necessary wiring requirements for your specific frame and handlebar set-up.
Given the challenge of sourcing GRX components, we are assembling these kits as items become available. Please know that some kits will come with the Shimano-boxed Lever with Caliper, while others may come with individually packaged lever, caliper, and hydraulic hose kit items. Detailed information for this kit is listed below.
