3 Notch:
The Blank Canvas
The 3 Notch is where your ideas take form — a titanium gravel platform engineered to be shaped entirely around you. Start with one of our proven stock geometries, then tune the details for your terrain, your fit, your riding style, and the bike you have always wanted to build.
Start with a proven shape. Make it entirely yours.
The 3 Notch starts as a clean titanium foundation, then becomes whatever you need it to be. Build it as a fast gravel racer, a long-distance all-road bike, a fully loaded bikepacking rig, or something completely your own.
Geometry, tire clearance, mounts, routing, finish, and component fit can all be tuned around the way you ride and the landscapes you chase.
Your dream bike starts with the details.
Pick from one of the stock geometries below, then decide what should stay, what should change, and what needs to be built around your riding style.
Not a stock frame. A starting point.
The 3 Notch is for riders who know a bike should match the person riding it. Instead of forcing your fit, terrain, and goals into a fixed production frame, 3 Notch gives you a proven titanium platform that can be shaped into the bike you actually want.
Custom Geometry
Start from a stock size or tune reach, stack, angles, chainstay length, bottom bracket drop, and fit numbers to match your riding position.
Custom Features
Add the mounts, routing, tire clearance, drivetrain compatibility, and fork details that make sense for your exact build.
Custom Purpose
Build it for speed, comfort, distance, bikepacking, racing, all-road use, or a balanced gravel setup that does a little of everything.
Stock geometry, ready to customize.
Use these numbers as the starting point for your 3 Notch build. The stock geometry below has been updated with a 415mm chainstay length and 395mm fork axle-to-crown.
