Road :: Stainless Steel

On perfect roads, in perfect conditions (with a perfect pedal stroke) your tires will stay stuck to the ground during even the most violent efforts. But perfect roads and perfect conditions don’t exist, especially in Boston. Roads have cracks, holes, and bumps. These imperfections steal your tires from the road, sap speed and power, and blur your bike’s intended sharp handling. This is where stainless steel shines.

The unique composition of Columbus XCr stainless steel tubing produces the spectacularly road-connected feel for which steel is famous. That connection keeps your tires on the ground, adding speed to every pedal stroke and inspiring confidence through fast corners. Meanwhile, the oversized tubes, drawn from a single billet into super light tubes with wall thicknesses as thin as 0.4mm, assure that every watt is transferred to your wheels.

We were among the first builders to work extensively with stainless steel bikes. Now we expertly use fully custom tube selection and geometry, including the first ever shaped XCr tubing, to dial the ride beyond any precedent. Our stainless road frame is a recognition that innovation and technology don’t have to come at the sacrifice of creativity, class, and craftsmanship. Let us make one for you. You’ll know what we mean.
