Kevin is more than a steel gravel bike. 

Magnificent and menacing, Kevin fears nothing and will take you places you didn't even know you wanted to go.

MEET MAGNIFICENT KEV!
The light but durable Italian Columbus Zona steel frame paired with the carbon GXR Seek fork has been proved on adventures all over the world: Jimmy Ashby rode his Kevin of Steel 39,100 km through 32 countries; Barrie Mead was the third place finisher in the 2019 Race to the Rock with his Kevin fitted with 650b wheels and 2.2” mountain bike tyres; and Curve crew have traversed New South Wales, New Zealand, Switzerland, Swaziland, Cuba, Croatia and countless other parts of the globe on this magnificent bicycle!

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 for One
Choose the wheels that suit your cycling style. Kevin can run either 700c wheels with 32–45 mm tyres for Road/Gravel/Cyclocross or go full Party Mode with 650b (27.5”) wheels running 1.8–2.2” tyres. You can even own a wheelset in each size and interchange them to effectively have two bikes in one.

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.

Adventure Ready
Kevin comes equipped with rear rack mounts, fender mounts & three bidon mounts and can be configured with either a 1x or 2x drivetrain. With huge tyre clearance across two wheel sizes, a longer wheelbase and a more stable platform, Kevin is perfect for day trips, weekenders and multi-day bikepacking.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.
