Steel Gravel Bike

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


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!

How much is a complete Kevin of Steel? We are offering a limited amount of complete Kevin of Steel bikes with Sram Rival 1, Curve 650b or 700c Grav AL wheels or $4,499. All other complete bikes will be priced as custom builds. Contact us or one of our stockists directly for a quote for your dream bike build.
How long will my Kevin of Steel take to ship? Early frameset orders will ship from March 2021, completes will ship from September 2021. Contact your local dealer for stock/availability.
What front rack can I run? If running a front rack on Kevin, please keep in mind that the fork is designed to carry a max weight of 6 kg (3 kg/ blade) - a bit of jiggery is required when installing a rack - you will need a bracket that allows that rack to attach to both the front and rear mount on the fork crown to ensure the rack is securely in place.
Is there much weight difference between the Steel and Titanium Kevin? The weight varies according to frame size etc. Generally the steel frame weighs around 30% more than the titanium frame of the same size. Steel frames range from 2.2–2.4 kg.
