Kevin of Steel is Back

Our favourite steel gravel bike is back with a new look. Introducing the mesmerising Ninja Mermaid colourway. This extraordinary hue is the ultimate chameleon, inspired by the depths of the ocean and the magic of legendary ninjas and mermaids.

Your ride will never be the same again.

At first glance, the Ninja Mermaid may appear almost black, cloaking Kev in a veil of mystery. But don't be fooled, for when the sun's golden rays dance upon the frame, a breathtaking transformation occurs. Suddenly, your Kevin of Steel glistens with an explosion of emerald green sparkles, shimmering like a treasure trove hidden beneath the waves. The iridescent sparkles reflect the sunlight like a thousand tiny mirrors, each casting its own spell, creating an ever-changing, dynamic visual symphony. You'll feel like you're gliding through an aquatic wonderland as you enter gravel paradise.

Ninja Mermaid is not just another paint finish; it's an experience that will transport you and your Kevin of Steel to a world of enchantment and adventure. Whether you're navigating urban jungles or tackling remote trails, this captivating hue will leave you and everyone you pass absolutely spellbound.

Ready for a slice of Kevin? Choose a steel frameset for your own project build or select from one of our battle tested complete bike options.

Italian Steel
The main frame triangle is comprised of Columbus Zona Italian-made double-butted tubing. Zona allows for the ideal compromise between weight, strength and life of the frame.
Two Bikes In One
The Ride 400 fork has clearance for wheel options based on your riding style. For example, Kevin can run either 700c wheels with 32–45 mm tyres, best suited for commuting, gravel, and cyclocross, or if you’re looking to tackle some rougher terrain with more traction, use 650b (27.5”) wheels fitted with 1.8–2.2” tyres. Curve has the above wheel options in both carbon and aluminum available.
No Weird Flex
The custom 4130 steel yoke design allows Kevin to run some super wide gravel tyres in two wheel sizes, and also stiffens the BB area to avoid frame flex under load.
Ready for Adventure
Our Ride 400 fork, originally titled GXR fork, was built to complement the Kevin of Steel and titanium GXR frameset. Featuring 3 x 12 mm M5 mounting points on each blade, the Ride 400 fork can accommodate anything from extra water bottles, our Rocket Pooches, or any other micro pannier or fork-specific bag.

There is ample room for bikepacking bags on all frameset sizes. To make sure current, prospective or custom bagging fits your frame size please see our Bagmaker Drawing page.
Want to Carry More?
With a range of different bike racks on the market, it is important to understand what products work with your Curve frame, and to mount them correctly. Before you do this yourself, we strongly recommend you get in touch with us regarding compatibility and best practices. Or we can install for you at Curve HQ.

most good looking bike out there

I just received my Kevin in the mail. It was the last in cream. It's a work of art down to the last details. Both in form and function. I live in Colorado USA and the biked arrive at my house safe and sound and the team at curve was awesome every step of the way. The bike arrived quickly. I did a lot of shopping around and was so happy to find this bike. I can't wait to hit the dirt roads with my new pal the Kevin.

Race, Ride, Seek ... a good credo!

The steel frame is beautifully finished. Even the weld seams around the bottom bracket are well done. This gives the bike a very clean look. The paintwork itself is gorgeous and varies between deep sea and starry night, depending on the light.
The handling on the road is smooth and stable. Off-road is where it really gets fun. The bike is surprisingly agile and "playful" ... Pure joy. The steel frame offers super self-damping. The handlebars and the many hand positions they offer are outstanding. Especially the control in the drops is brilliant! My new favourite position on descents: lots of control. The SRAM Apex 1x12 (mech.) shifts cleanly and precisely. At first I was worried about the number of gears. But the 10-52 cassette takes you up and down everywhere. Thanks to the massive tyre clearance, even muddy tracks are no problem and accumulating dirt doesn't get in the way and grind. The many mounts on the frame allow for various equipment and increase the versatility of this bike.
Last but not least: praise for the communication (via email) across time zones and continents! I was able to contact you at any time with questions and uncertainties and you responded faster than some local authorities.
Vielen Dank!

Kevin Heaven

I've had my Kevin of Steel for almost 5 years now so I reckon I'm overdue a review. Always up for anything, Kevin is the enabler of adventures and has never complained once. Kevin is my go to guy for commuting, errands, all day gravel loops and trips to the pub. Loaded up or in race mode this bike is sturdy as heck yet somehow zippy and turning heads wherever we go. Rolling out for a ride with Kev still makes me smile every time, I reckon we'll be friends 4eva.

Kevin

I have ridden so many bikes, and just can’t get over how comfortable and well made my Kevin is. I’ve used my Kevin of steel for commuting, bike packing, gravel rides and even bunch road rides with my local group.

I love my Kev so much that I had to pull the trigger on a second frameset in camel cruiser, that I will build up to be my forever bike.

I can never go back to carbon or aluminium frames

Kevin of Steel aka Heidi

I absolutely love my Kevin of steel aka Heidi. There is a good reason why this bike is called the Swiss Army Knife of bikes. Hence my Heidi is the weapon for any adventure. From the commute to work to the wilderness of Victoria, Heidi doesn't miss to put a big smile on my face.
