Nature Boy 853

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. 9 Thru-Axle 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 undisputedly among the worlds best, and 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 NB853 retains all of the All-City custom touches you’ve come to expect: 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.
