The AC series, the original track frame of San Francisco instigator MASH, which creates a spark in the motorcycle scene all over the world, is back again this year!

Custom built AC-3 using Columbus 7005 series Airplane tubing. Painted in gloss black with stunning graphic work by Al Nelson.

The 1 1/8"-1 1/2" tapered fork is a completely original carbon monocoque that was worked on from scratch. In addition to being extremely rigid and extremely lightweight, the unprecedented 30mm rake angle will enable sharp cornering.

Guides for retrofitting brakes are hidden in the smoothly finished fork crown and rear bridge. It will look cool with either brakeless or full brake.
As with the AC-2, it also has a bottle mount for quick hydration.

For those who love criterium and want to run like an arrow through the streets.
For those of you who have been looking for a frame that responds directly to the distance.
Find the style that works best for you.
