Description
This GRX 810 Mechanical 11-Speed kit is an Excel Sports package of several specific GRX items required to build a 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. The cassette included is an 11-34T HG800 for max range with the 2x11 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 is listed below.
