Are all Shimano groupsets compatible?

When SRAM entered the road groupset market in 2006, it decided to adopt Shimano’s specifications for its chains and cassettes. As a result, the chains and cassettes from the two brands have always been completely interchangeable for any given type of transmission (e.g. 11-speed).

Can you mix GRX and ultegra?

Is Shimano GRX good for road?

With GRX I can keep that aero position on the hoods and still be able to ride comfortably on singletrack. I am a big fan. The brakes are essentially rebadged road brakes, but Shimano makes a great road brake and they were powerful enough to stop me even with a full bikepacking load.

What cassettes work with GRX?

GRX utilises 2 types of cassette, the double system will use a narrower spread road range cassette in ratios of 11/32 or 11/34. The 1x system will be equipped with an MTB style cassette with a wider ratio of 11-42 or thereabouts.

Are all cranks interchangeable?

Cranksets are not always interchangeable. Every crank is designed to work with a specific bottom bracket. Even if the cranks use the same interface (octalink, square taper, or hollow tech), switching them between bike brands or even models of the same brand is hard. MTB cranks are usually spaced wider than other bikes.
