URBAN CROSS MACHINE

Featuring the 2-For-1 Dropout, our elegantly designed combination geared or single-speed sliding dropout system, the Super Professional can be converted from single-speed to geared as the city streets transform into your own concrete cyclocross course.

ELEGANT SUPER COMMUTER

Informed by our famed cross geometry to be fast, responsive, agile, and capable on mixed terrain, the Super Professional is a full-on everyday destroyer loaded with mounts for racks, fenders, two bottle cages, and all the versatility commuters and daily riders demand.

When you buy a bike from Aventuron, not only will your bike ship for free, but you will receive a bike that is ready to ride out of the box.

We assemble and tune your bike, then repackage it to ship. When you receive your new bike it will be very easy to assemble. You will have to attach the front wheel, handlebar, seatpost and pedals. Most bikes do not include pedals, but we have an extensive pedal selection. We are a family-owned and operated business and look forward to having you as a customer.

We’ve carefully chosen every piece of tubing on every frame size to provide the best ride possible.


MOUNTS FOR FENDERS AND RACKS IN FRONT AND BACK

Conquer wet roads, loaded urban commutes, and whatever else you can dream up without missing a beat.

Built to accommodate 700c x 45mm or 650b x 47mm tires.

SIGNATURE DETAILS

Our mission is to bring beauty back to production bicycles. This means investing in custom touches that elevate the whole. We devote time and resources to signature details that turn heads and signify high-quality craftsmanship. These elements tell a cohesive visual story and form a distinct silhouette so that even if your unique bike were stripped down to bare metal, it would still be instantly identifiable as an All-City bicycle.


SIGNATURE FORK CROWN

Featuring All-City’s first custom fork crown, elegantly outfitted with four-point rack mounts.


MASTER DROPOUT

Convert from single-speed to geared and back again with our beautiful, cleverly designed sliding dropout system.


REINFORCED BOTTLE BOSSES

Beautiful stars reinforce a pair of bottle bosses and our obsessive attention to detail.


LIQUID PAINT AND E.D. COAT

Our topnotch wet paint finish sparkles with depth and luster, while an E.D. coating protects against rust.


SIGNATURE SEAT COLLAR
