Cyclocross Frames

All-City Nature Boy A.C.E. Frameset
$1,299.00
A singlespeed cyclocross sibling to the Macho King A.C.E., the Nature Boy A.C.E. comes primed for racing, covering quick up-and-downs, and cutting through the gnarliest of courses. Now crafted from A.C.E tubing — All-City’s proprietary air-hardened, custom-designed, extruded steel tubing — the Nature Boy’s expertly engineered butting profiles and wall diameters provide advantages that even the most excellent off-the-shelf tubing just can’t match. Stronger, lighter, quicker, and stiffer than ever, it’s simply unlike any other singlespeed in the world. Featuring modern race geometry and an ovalized top tube for easy shouldering over obstacles, we’ve increased the Nature Boy’s mud clearance to eliminate unnecessary pit stops on the course. Built with an Eccentric Bottom Bracket to manage the chain tensioning, a shortened chainstay, and replaceable derailleur hanger, we’ve also outfitted the Nature Boy with a Columbus Futura carbon fork with adjustable rake, tapered head and steerer tubes, and clearance for 700c x 42mm tires. With a fresh Fulton green and black splatter paint job, all the All-City custom touches you’ve come to expect star here too, including custom seat collar and dropouts, flat-mount brakes, and star reinforcements on the bottle bosses and fender mounts. For steel lovers starving for competition, these updates to the Nature Boy are destined to get you across the finish line faster than ever before. - A.C.E steel tubing: All-City’s proprietary air-hardened, extruded steel tubing, custom designed to be lighter and stronger for riding and racing - Contemporary race geometry, raised bottom bracket, shortened chainstay, and increased mud clearance - Ovalized top tube for easy shouldering over barriers - E.D. coated for durability and rust prevention - Built-in seat clamp and internal rear brake cable routing - Columbus Futura carbon fork with adjustable rake - Fits 700c x 42mm tires
All-City Nature Boy Disc Frameset
$782.00
The disc brake version of All-City's iconic Nature Boy singlespeed cross frameset. Like its cantilever brethren, the Nature Boy Disc carries all of the AC hallmarks that you've come to expect: beautiful lugged fork crown, custom dropouts, custom BB shell, signature head badge, and an E.D. coating for rust protection. It has proven race-inspired geometry in a durable 612 chromoly steel frame with chromoly tapered fork, and since you'll want to ride this cross bike every day, it's got plenty of room to fit large tires and even fenders. For racing, cruising trails, gravel, or daily commuting, disc brakes and a single-speed setup provide unmatched control and reliability.
All-City Macho King A.C.E. Frameset
$1,299.00
Every champ has got to face a challenger at some point, and with that in mind, we’re not about to just let someone steal the cyclocross throne from the Macho King. Back for a title match wrapped in a new yellow and black splatter colorway, the Macho King is flush with special touches destined to shine both on the course and atop the podium. Designed to provide speed and agility between the tape, it’s built from A.C.E tubing, All-City’s proprietary air-hardened, custom-designed, extruded steel tubing. While excellent off-the-shelf tube offerings have their time and place, using A.C.E. here allows our engineers to go completely custom with the butting profiles and wall diameters—helping them produce a lighter, stronger, stiffer, and faster course crusher, unlike anything else out there. Boasting contemporary race geometry, English-threaded bottom bracket shell, shortened chainstay, replaceable derailleur hanger, and substantial mud clearance, the Macho King now features a Columbus Futura carbon fork with adjustable rake, tapered head and steerer tubes, and clearance for 700c x 42mm tires. It retains all the All-City custom touches you’ve come to expect, such as custom seat collar and dropouts, flat-mount brakes, and star reinforcements on the bottle bosses and fender mounts. This generation of the Macho King is the choice for steel lovers with a thirst for competition, so get out there, break some hearts, and separate the contenders from the pretenders. - A.C.E steel tubing: All-City’s proprietary air-hardened, extruded steel tubing, custom designed to be lighter and stronger for riding and racing - Contemporary race geometry, raised bottom bracket, shortened chainstay, and increased mud clearance - Columbus Futura carbon fork with adjustable rake - Fits 700c x 42mm tires
