ALL-CITY Super Professional Frame Set

On the street or in the mountains, singlespeed or geared.

A versatile bike for free-spirited riding: The All-City "Super Professional"

Based in Minneapolis, Minnesota, at the northernmost edge of the U.S., All-City is a brand that offers a diverse range of models from track bikes to gravel, urban, and all-road bikes.

They openly declare themselves a "party brand," prioritizing an attitude that finds genuine joy in riding. Yet, behind that fun lies a solid design philosophy and a meticulous attention to detail.

Their chromoly frames, which balance low weight and durability, feature All-City’s proprietary "612 Select Tubing." Named after Minneapolis’s “612” area code, these double-butted 4130 chromoly steel tubes are optimized for each size and model, offering both a comfortable ride and rugged toughness.

Enter the "Super Professional" from All-City.
The greatest appeal of this model lies in its versatility, offering the freedom to be built as either singlespeed or geared.

All-City’s original "2-for-1 dropout" allows for singlespeed setups without a chain tensioner, while also accommodating a derailleur should you choose to swap the rear ends. It is fully customizable to suit your style and usage, from city commuting to weekend gravel rides.

Furthermore, the frame and fork are equipped with eyelets for fenders and racks, making it flexible enough for daily commuting, touring, or gravel riding. Internal routing for a dropper post is also provided behind the seat tube, allowing for upgrades to a full-fledged off-road specification.

The geometry is race-inspired. It offers a nimble, responsive ride while remaining comfortable and manageable for everyday use.

The Super Professional is a bike that brings style and functionality together at a high level.
On the street or in the mountains, ride your own way—
Experience the "freedom" of the ride that All-City delivers.
