All-City's Big Block


Like the steel skeleton that supports a skyscraper, the raw marble slab that’s shaped into a sculpture, or the base spirit that gives a cocktail its backbone, the foundation of every All-City bicycle is the frame. And whether yours is destined for high speeds on smooth pavement, soaking up chatter over long stretches of gravel, or helping you podium at your next cross race, we’ve built it up with strong, gorgeous, high-quality tubes uniquely suited to the task at hand. These are our frame materials of choice:

A.C.E. Tubing is used for All-City's Cosmic Stallion


In our never-ending quest to produce the finest production steel bicycles, we recognized an opportunity in 2016 to expand our capabilities and finally design our own custom tubeset. The result was A.C.E., our proprietary air-hardened, custom extruded steel tubing — tubes made especially for each unique bike.

When a project in development calls for the thinnest walls attainable while still maintaining strength and weight targets, A.C.E. allows our engineers to go completely custom with butting profiles and wall diameters from the main tubes to the stays. That’s right, full-frame heat treating and customization!

In a world where steel is often considered a retro material, A.C.E. is lighter, stronger, better-looking, thoroughly modern, and completely unique.

612 Select

With a nod to the Minneapolis streets, alleys, and trails we call home here in Area Code 612, 612 Select is the name we’ve given to our proprietary blend of double-butted 4130 Chromoly steel tubes.

With ride quality and durability at the forefront, we’ve selected these tubes for their specific diameters, wall thicknesses, and butting profiles. And to get the feel of each bike just right, we’ve chosen every piece of tubing on every frame size specifically for that bike’s intended use and the projected size of the rider.

You see, even when we’re developing a bicycle that doesn’t call for a completely custom steel tubeset, we still spend a borderline unhealthy amount of time designing our frames. We do this to ensure that each size of every model is precisely tuned to give you the experience and thrill you’ve come to expect from All-City Cycles.

Aluminum is used for All-City's Thunderdome


More than 40 years after aluminum was first used as a bicycle frame material, aluminum alloys remain incredibly attractive to speed-obsessed riders like us who dream of breaking the sound barrier.

Light, strong, and stiff, aluminum is used across a range of frame styles from road to mountain to track. As a result, we’re often able to source precisely the tube profiles we want from industry partners. That won’t stop us, however, from custom-designing aluminum tubes when we feel it’s appropriate to go deep on a bicycle in development.

With both approaches providing reliably stellar options for our bikes, we’re able to build damn fine aluminum steeds that help enhance what this material — and the riders who love it — are able to do.
