CURVE - Kevin of Steel III


KEVIN of Steel III is HERE!

Kevin is more than a steel gravel bike. 
With the ability to run different sized tyres (650b & 700c) and whole lot of mounting options, there’s never been a more versatile bike for mixed terrain cycling. When dressed in 700c wheels, Kevin loves walks on the beach, fast gravel rides, road touring and even cyclocross racing. In 650B ‘party mode’, he's always up an adventure, like fun singletrack, trail riding, bikepacking, overnighters and more.

Stock is extremely limited. Please get in touch for availability.

Kevin III will have all of the same great features of the previous Kevin of Steel, with a couple of awesome updates:

XS & SM Kevin of Steel III will now have a sloping top tube for improved standover clearance, and lower bidon cage mounts for more frame-bag space.

Kevin now comes in two new and exciting colours: Handsome Blue & Hero Green.

We only have stock of framesets remaining.

DELIVERY UPDATE: We only have a few sizes remaining from this first batch! Get in touch for details. Batch 2 is due March 2021.


Oh look it’s Kevin of Steel III, and he put mousse in his hair! 

Put a clean shirt on and get ready to meet your new BFF, your SO, your Ride Or Die. His name is Kevin, he loves to party, the great outdoors and he’s got buns of steel! This could be the beginning of the endless #summerofgravel for you and Kev. Oh yes. OH YES! 



The main triangle is comprised of Columbus Zona Italian-made double-butted tubing. Zona allows for a reasonable compromise between weight, strength and life of the frame.


Choose the wheels that suit your cycling style. Kevin can run either 700c wheels with 28-45mm tyres for Road/Gravel/Cyclocross or go full Party Mode with 650b (27.5”) wheels running 1.8–2.2” tyres. You can even use two sets of wheels on the same bike to effectively have two bikes in one.

Kevin is not quite like other bikes: he’s a little longer and a little taller to create more space for frame bags and 1L water bottles. XS and SM Kevin of Steel III now have a sloping top tube to allow for more standover height, and lower bidon cage mounts for more frame-bag space. The general rule is that a Medium Kev is the equivalent size to a standard 54cm frame. Kevin is designed to run a shorter stem and wider drop bars to maximise handling efficiency.

Keep in mind that gravel bike geo is not that same as road bike geo, so the numbers on the chart may blow your mind. Get in touch if you need help with sizing -

Our Kevin of Steel is here ready to save the world.

Have you ever heard of a titanium superhero? No, Superman is the man of S_T_E_E_L. While our Ti Kevin is staring in the pond, Kev of Steel is defending the planet from baddies. While Ti Kevin is busy grooming, our steel hero is defeating dictators and saving kittens from burning buildings.

Titanium may make a nice piece of jewellery, but swords are made of steel, and are the most honourable of weapons, reserved for nobility. Whether you’re protecting an empire, performing a decapitation or conducting a ritual sacrifice, steel is your material of choice.
