Shimano launched a new gravel groupset with plenty of gearing options this year, and it's already making its way onto bikes you can buy right now. If you're in the market for a new bike equipped with GRX, we've rounded up a load of top bikes you can buy right now. We'll update this list as more new bikes are announced.
To recap, GRX is Shimano's first dedicated gravel bike groupset. It's available at three price levels - 800, 600 and 400 - roughly related to Ultegra, 105 and Tiagra respectively. There are 2x and 1x options, 800 and 600 are 11-speed and 400 is 10-speed. Cassettes come from existing road and mountain bike catalogues, and max out at a recommended 11-34t for 2x and 11-42t for 1x.
From compiling this list, it is clear manufacturers aren’t afraid of mixing the different groupsets. Some bikes have upgraded shifters, cranks and derailleurs, with some downgrading the crankset, shifters or cassettes, all in an effort to deliver a bike at a target price point.There is one limit to this interchangeability. You can’t mix and match GRX chainsets and front mechs though. To accommodate wide tyres, Shimano has pushed both outboard by 2.5mm.
The new groupset is dropper post friendly with a dedicated lever when using a 1x setup to control the seatpost. There are also in-line brake levers, so you can operate the brakes from the top of the handlebars. Shimano has also launched new wheels as part of the GRX range.
With cyclocross season in full swing, here’s Scott’s race-ready Addict with a GRX800 Di2 2x groupset, using a 48/31t chainset and 11-34t cassette. Tyres are the excellent Schwalbe G-One 35mm tyres on Syncros Capital 1.0 carbon wheels.
The Speedster is a more versatile bike with a lower entry price, aimed as a versatile do-everything bike. The aluminium frame and carbon fork have mudguard eyelets and there’s plenty of space around the 35mm tyres. Groupset is a mix of GRX400 and GRX600 with a 46/30t chainset and 11-34t cassette.

The Grail CF SL has a frame that is near enough identical to the CF SLX, it’s just the carbon fibre layup that is different to save some money with a small weight penalty. This is the cheapest GRX bike with GRX600 mechanical shifters and crankset, but upgraded GRX front and rear mechs.
