The Merlin GX-01 is our super-lightweight high-performance carbon gravel bike designed for mixed-surface adventures straight from your front door. Packed full of technical features the GX-01 has been designed from the ground up to excel on a wide variety of terrain. From fast, smooth tarmac to demanding gravel tracks and trails this bike feels equally capable and handles brilliantly regardless of what you throw at it.
Key features of the Merlin GX-01 carbon gravel bike includes considerable tyre-clearance in the rear of the frame; thanks to its bridgeless seatstays and chainstays the GX-01 will easily accommodate up to a 40mm gravel-specific tyre allowing you to run lower tyre-pressures and providing you with more comfort and enhanced traction when you’re negotiating lose gravel surfaces. Up front the full-carbon GX-01 fork offers the same amount of tyre-clearance while front & rear thru-axles help to ensure that your wheels are always secure, brake rotors are perfectly aligned with the calipers every time and there is no annoying brake rub. The GX-01 thru axles also add stiffness between wheel hub and frame with a noticeable increase in steering precision from the fork.
The Merlin GX-01 carbon frame and fork features internal cable routing throughout, keeping the silhouette of the bike simple and clutter-free while protecting gear cables from getting fouled up with grit and grime. We’ve specced the GX-01 with a threaded bottom bracket shell to allow you to quickly and conveniently change the bearings without the need for expensive press-fit bearing tools. Slim seatstays provide a little bit of extra compliance keeping you comfortable on rough surfaces and a large bottom bracket area creates a super-stiff pedaling platform, allowing you to transfer all your power to the rear wheel during fast road sections and super-steep, lose gravel surfaces climbs off-road.
The Merlin GX-01 carbon gravel bike features Shimano’s excellent new 105 R7020 11-speed hydraulic disc brake groupset which features a new Shadow Technology rear derailleur that gives a lower profile and increased protection from crash damage as well as a great looking chainset evolved from the Ultegra R8000 version which is even stiffer and provides more power transfer than its predecessor. With a wide range of gears available you’ll be able to ride more economically regardless of the terrain, leaving your legs feeling fresher for longer. The addition of safe, easily-modulated Shimano BR-7070 flat-mount hydraulic disc brakes will have you descending with new-found confidence. A choice of finishing components lets you customise the finer details of this great handling carbon gravel bike before our Merlin workshop technicians custom build your bike to your own spec. Choose your preferred wheelset, tyre choice, stem-length, handlebar profile, the gear ratios of your cassette and chainrings options and more to tailor your dream carbon gravel bike specifically for you.

GavinBought this bike with the optional upgrade of Fulcrum 4 DB wheels and Panaracer Gravelking tyres to replace my worn our Raleigh Roker Pro. Just had my first ride and my impressions are excellent. It is lighter than the Roker, which has a 1x system, and feels more lively. Handling is fantastic although I haven't been anywhere too technical yet. Shimano gearing is in .y view better than Sram 1x in three key areas: it will wear less, does not have lever rattle and does not get upset by mud in the chain / rear gears. I have fitted guards front and rear, unlike some official review comments it has fittings for full front guards. No rear fittings but SKS clip on guards are almost as good as a full rear anyway and easy to remove for dey days. Couple of final comments, threaded bottom bracket is great to see as we live in the UK not California and they are so much more robust that press fit. Finally it weighed in a c8.5k as built without pedals / guards which is pretty competitive in my experience. My Roker was c9kg with Hunt wheelset. I do think the Merlin frame is more lively and better for climbing than the Roker bit I think the Hunt Wheels outperform the Fulcrums by a reasonable margin. I'll be swapping them over to see if that is the case. Overall a great bike that performs very well: certainly punching above it's weight value wise.
Mr PowellBought he GX-01 in March 2019 with Shimano 105, Fulcrum Racing Sport 77 and Schwalbe G-One Allround Performance RaceGuard 35mm tyres. It’s been great on all surfaces since I collected it. I’ve ridden over 4,000km in 5 months. Comfortable, light and responsive. I use it for regular runs of over 100km and I’ve just returned from a 5 day tour of northern France where it had to cope with tarmac, gravel and forest tracks and it performed well on all. I was slightly concerned about buying a carbon gravel bike that would be more fragile but it’s coped well with everything I’ve thrown at it.
The only thing I have changed is the tyres, I’m now on Panaracer 38mm gravel tyres which seem to run easier and have increased the comfort. I would have liked would have had rear mudguard/carrier mounts for all day rides. I assume they are only on the front because of off the shelf forks which already have them. Matt black finish looks great but does show up every little scratch and water mark.
Overall 5 stars, my criticisms are minor. It’s a great bike.
Mr HemmingThis is the bike for every occasion.
I sold my GT hard tail mountain bike and my Bianchi road bike to buy something that was diverse and flexible, and that would taylor well with the different cycling I did. I saw that gravel bikes were a thing so I did some research into them to see what they were all about. It seemed like for someone who cycled roads and gravel paths they were a good choice. Long gone are the days where I do jumps on my bike, but I do love a good off road circuit. I also love the speed and responsiveness you get from a road bike. This seemed like the best choice for both!
Frame and forks -I wanted carbon, due to the comfort and weight benefits. The carbon frame on this bike is heftier than my previous road bike, and as a result does weigh more. However, you want something that can take the punishment of dirt tracks without having to worry about the frame fracturing. Its responsive, flexible, sturdy and light compared to other aluminium frames. The forks offer nice comfort whilst going down gravel paths or bumpy roads. All in all Merlin have done a great job working out the geomatry offering a good mix of performance and comfort. The through axles work a treat. I get home after a muddy ride and take the wheels off to wash the bike, then put them straight back on and almost every time the disc rotors are perfectly aligned with the calipers. Theres also a mount for mudguards on the front forks, and room for some on the rear if you want to fit them on.
Wheels - I went for the fulcrum DB4 and im not disappointed. They are sturdy, aero for alloy wheels , look great and are a reasonable weight. Theyve been up and down hills, holes, ditches and they still run true.
Groupset - I opted for an Ultegra rear diraleur (mainly because it was the only one available ) and shifting is silky smooth and responsive. I got the 11-34 cassette, which offers an impressive gear ratio. The 34 comes in handy heading up those climbs, whilst the 11 offers great speed on the descents. I opted for the 36-52 chainset which gives a good variety of range with the rear cassette. I upgraded to the Ultegra brake rotors which work and look phenomenal. The hydraulic brakes from the 105 calipers are very good. The whole 105 groupset is impressive, offering bullet proof shifting and performance. Shimano have done a great job with this new groupset!
Tyres - I opted for the Schwalbe G-one all round performance 38mm and theyre so impressive both off and on road! They roll nicely on tarmac and on gravel, offer great traction and are nice and comfortable. Definitely a good choice with this bike.
Finishing kit - I mostly went with Fizik and it looks great on the bike. No regrets here!
Conclusion - this bike is incredible if youre a roadie looking for versatility, or a mountain biker looking for faster sections on the simpler trails. You could use this bike for cyclocross if you wished. Its sturdy, comfortable, responsive and quick. Merlin have done a great job balancing this frame to cater for a wide range of terrain and occasions. I bought some Continental GT5000 28mm tyres as well, so when im going out on just the road I can put these on and roll faster and smoother. It really is the Swiss Army knife of bikes. Thanks Merlin!
