If single speeding is your thing, this is the one.

The race version of our Nature Boy disc platform features our new singlespeed disc dropout, Reynolds 853 tubing, a Whisky No. 7 cross fork and hydraulic disc brakes.

We are particularly proud of our new singlespeed disc dropout as it solves our main frustration with dropouts of this style: where do you position the brake caliper for optimum performance? The answer was to develop a proprietary system where the tension screw is used to pull the caliper mount into the correct position. Just loosen everything up, use the tensioner to achieve desired chain slack and tighten it all back up. No more guesswork, just reliable braking performance.

Reynolds 853 tubing is, in our estimation, the finest steel going. Nothing holds its value like high-end steel. It's lightweight, will last forever if treated properly, and produces the finest ride quality of any material used in the bike world. Twenty years from now this frameset will still be fawned over by bike geeks due to that little Reynolds sticker.

The Nature Boy 853 comes with a 44mm headtube and Whisky No. 7 carbon fork with a tapered steerer tube. The fork saves about a pound and a quarter over our excellent steel variant.

It retains all the All-City custom touches such as: signature dropouts, signature seat collar, custom English threaded bottom bracket shell, reinforcements on the bottle bosses and fender mounts. It has clearance for 38's, plus room for tons of mud. Our proven cyclocross geometry and the All-City name back it all up.
