Road Shimano Build Kits

The success of Shimano's 11-speed GRX gravel components in both 1x and 2x With the GRX Limited Edition series, Shimano has created a special edition silver finish that embraces the beauty of aluminum. It perfectly complements the efforts of the frame builders who blend the aesthetic form of their creations with the inherent beauty of their metal materials of choice. It can also ideally complement carbon bikes, especially all, or nearly all, black or natural carbon finishes. The bold silver finish evokes the past, but the design, performance and capabilities will carry you to far locations whether fast or at a more leisurely pace.

The GRX Limited Edition Groups feature the same component build as the GRX-810 series, but with the spectacular LTD finish. This item is the 2x11 drop bar version. A 48-31T chainring combination is ideally matched for range and speed with an HG800 11-34T road/gravel cassette. Drivetrain and braking-wise, this package has everything you need except disc brake rotors (often selected by rider preference) and a 24mm Shimano compatible bottom bracket, which will be specific to your frame. Detailed information is listed below. A limited number of these groupsets was created by Shimano, so if you are interested we recommend you don't consider your options for too long.
