27 of the hottest 2021 Shimano GRX bikes

Want Shimano's GRX gravel bike groupset? Explore your options and get the best Shimano GRX bike with our guide

Shimano's GRX gravel bike component series has been a definite hit thanks to its range of gearing options and tweaks to accommodate fatter tyres than you'll find on road bikes. But it was launched a little late so not every bike maker got on board for the 2020 model year. That's changed for 2021; GRX is everywhere. Here's a selection of Shimano GRX-equipped gravel bikes, cyclocross bikes and adventure bikes that we like.

  • Intended for gravel bikes, Shimano GRX is a not so much a single groupset as a series of components from which manufacturers can pick and mix

  • As well as gravel bikes, GRX is being used for cyclocross race bikes and for bikes that veer toward the 'touring bike' end of the touring-adventure-gravel spectrum.

  • GRX was announced surprisingly late in 2019, making it hard for the very largest manufacturers to choose it, but we expect to see GRX bikes from Trek, Specialized and Giant for the 2021 model year

  • Bikes with Shimano GRX start around £1,200

27 of the hottest bikes with Shimano's GRX gravel bike components

To recap, GRX is Shimano's first dedicated gravel bike groupset. It's available at three price levels — 800, 600 and 400 — that roughly correspond to the Ultegra, 105 and Tiagra road bike components 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 levels of GRX. 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.

Specialized Diverge Expert Carbon 2021 — £5,250.00

2021 Specialized Diverge Expert Carbon

We have, it's no secret, a long-standing deep and frankly borderline indecent relationship with Specialized's Diverge gravel bikes, so we're excited to spend more time with the 2021 models with their revamped geometry, Future Shock suspension and 47mm tyre clearance. Give us free choice and we'd be very tempted by the second-from-top model in the range with GRX Di2 gearing and that amazing paintjob. Yum!

Boardman ADV 9.0 2021 — £1,800.00

2021 Boardman ADV 9.0 3

Boardman are offering two GRX-equipped bikes for 2021, and this is higher spec 9.0 model is configured with a 2x, 46/30 chainset to provide a top end just a little larger than a 50x12 gear. Boardman has slackened the head angle compared to the previous version, elongating the top tube and lowering the bottom bracket—all in the pursuit of a confidence inspiring, stable ride. A shorter stem should make the handling “on the agile side of neutral”, according to Boardman.

With 700c x 38mm tyres, Boardman says the zippy build is intended to "balance efficiency on the road as much as off it”; although for some extra robustness, Panaracer's Gravel King SK tyres are specced front and rear to “strike an excellent balance between rolling resistance on smooth surfaces and grip when things get looser”. Tubeless valves are supplied as standard for easy conversion, and the subtly flared bars should provide plenty of technical control without compromising too much aero efficiency when you're bombing it along the road.

Trek Checkpoint ALR 5 2021 — £2,150.00

2021 Trek Checkpoint ALR5_

Someone has to make do-everything gravel bikes at sensible prices, and who better than Trek? The Checkpoint ALR 5 has a mix of GRX 600 and 800 on an aluminium frame that boasts clever details like the Stranglehold adjustable dropouts that let you tweak the rear wheel position to adjust the ride.

Giant Revolt Advanced Pro 1 2021 — £4,899.00

2021 Giant Revolt Advanced Pro 1

Tester Stu really liked this bike's 202 kid brother, saying "Not only does the Revolt look purposeful with its boxy carbon fibre tube profiles, it rides that way as well.

"The harder you ride it, the more you get back. I spent huge sections of my rides through wooded trails or twisty gravel byways knowing that I was so close to the bike's limits that it could all go pear-shaped in an instant.

"I just couldn't stop it, though – it was addictive."

With a lighter frame in a higher grade of carbon fibre, the Revolt Advanced Pro 1 should be more fun than a barrel of monkeys.

Merlin Malt G2X GRX 2021 — £1,189.15

2021 Merlin Malt G2X GRX.jpg

Lots of the bikes in this list are quite spendy, but here's Merlin Cycles with the antidote to top-dollar GRX-equipped gravel bikes in the aluminium-framed, GRX600-equipped Malt G2X.

The Malt boasts "neutral and balanced handling, which makes it ideal as a first graveller, or a bike for those who enjoy spinning for hours offroad without having to focus too much on what's going underneath the tyres. You can just kick back and enjoy the scenery."

Van Rysel EDR CF 2021 — £1,899.99

2021 Van Rysel edr cf grx gravel bike

Probably the biggest bargain out there, this gravel bike from French-based sports superstore chain Decathlon has a mixture of GRX 800 and 600 driving a 1X transmission for simplicity. Decathlon claims frame and fork weights of just 1,020g and 340g respectively, making the EDR CF an enticing prospect for long-term upgrading.

3T Exploro Max GRX 2021 — ~£4,000

2021 exploro max grx 2x

It caused a shock when it launched, the 3T Exploro dared to be different, bringing aerodynamics to the gravel bike market. For 2021 3T have turned it up to 11 with the Exploro Max, an aero gravel bike that'll accommodate whopping great 650B 61mm tyres, a size that not very long ago meant you were looking at, well, a mountain bike. What the  Exploro Max really resembles is the home-grown 'monstercross' bikes various tinkerers have been creating in their sheds for the last few years, cramming the fattest possible tyres on to drop-bar bikes, some of them built on frames that did start life as mountain bikes.

Genesis Croix de Fer Ti 2021 — £4,599.99

2021 Genesis Croix de Fer Ti

British company Genesis wasted no time in equipping its very lovely titanium Croix de Fer bike with the latest GRX groupset, but for 2021 they're really pulled out the stops with a revamped Croix de Fer Titanium aimed solidly at everyone who wants to travel light and fast. Wherever you like to mount bikepacking or touring luggage on your bike, the Croix de Fer Titanium probably has a mount for it — there are at least 20 mounting points on the frame and we keep losing track when we try and count them.

The components are all from the GRX810 hydraulic line, with a 2x setup, using the 46/30 chainset paired to an 11-34t cassette. Tyres are 40mm wide Kenda Boosters.

Shand Stooshie — £3,395

Shand Stooshie.jpg

The Shand Stooshie is a comfortable and relaxed-handling all-road and occasional gravel bike with enough versatility to serve multiple uses.

This is a bike that feels right at home cruising along country lanes, with a big route planned that may or may not include some forays into the wilderness via forest tracks and abandoned byways.

It's a comfortable bike for going the distance, the skinny steel tubes and big tyres helping to soak up vibrations effortlessly. It still impresses us that despite modern material and technology advances, a really good steel frame can be so silky smooth.

Merida Silex + 8000-E — £3,300

2020 Merida Silex + 8000-E side view on white

Alongside the 'classic' Silex with 700C wheels, Merida now offers a version with 650B wheels, allowing for fatter tyres for more adventurous off-road shenanigans. The platform "offers quick handling, making it feel superbly controllable on demanding terrain," according to tester Mat Brett. "Quite an upright riding position helps here too. Rather than going into technical sections head first, you feel like you're sitting high, easily able to survey everything ahead of you and react accordingly."

With GRX 800 Di2, the Silex + 8000-E is the top model in the range. If you want something financially more conservative, check out the £1,400 aluminium-framed Silex 400 with GRX 400 components and 700C wheels.

Enigma Escape.jpg

Enigma's updated Escape titanium gravel and adventure bike is now being offered with Shimano's new GRX groupset, and we've tested the bike pictured above.
