Built for Big Rubber and Big Rides
Clears 2.2" tires in all sizes. Built from day one to let you run the tires you want, not just the tires you can squeeze in. The front fork opens up tons of possibilities- dynamo wiring, racks, you name it.

Big Tires, Big Fun
The Build
A no-compromise gravel machine built for performance, no matter what that means to you. Nab podiums, cross expanses, or drop your friends on the group ride.
A mix of the best steel tubing money can buy and dialed-in geometry, with custom sizing to fit you like that pair of boots you should've thrown out.

Clears 2.2" tires in all sizes. Built from day one to let you run the tires you want, not just the tires you can squeeze in. The front fork opens up tons of possibilities- dynamo wiring, racks, you name it.
Extensive use of 3D printing where it matters, and top spec Reynolds 853 where it doesn't. Fully parametric design means each bike is totally optimized for you. Custom UDH dropouts, T47 bottom bracket, and standard 27.2mm seatpost for maximum compatibility. 50T 1x chainring clearance just in case you're a beast.
A blank canvas so you can run whatcha brung. Mechanical shifting? Rack/bottle mounts? 2x? Suspension fork? Let's make it happen. If it's not listed, it's just because I haven't heard it yet- everything is on the table. Eccentric Bottom Bracket option for singlespeed builds is ready to go. Custom paint means anything from mild to wild aesthetics.
Brass Tacks
What's included
Here's your starting point. Pricing on high complexity multi-color paint jobs, extensive braze-ons, or changes to the build spec (suspension forks) are done case by case, but don't be afraid to ask! $500 deposit is due once geometry and manifest are developed and agreed upon. I will work with you on your goals for the whole build, including specifying all the necessary components, working with parts you have, etc. If you buy parts (stem, hubs, etc) to go with the bike, I'll paint match it to the frame!
