*MASH* AC-4 frame set (neon algae)

MASH a legendary fix gear crew from San Fransisco, CA. Since founded in 2005, they have grown as one of the biggest fixed gear cyclists community in the world.This is their 3rd edition of “AC”, their aluminum aero tubing track bike frame series.Their 1 1/8″-1 1/2 tapered monocoque carbon fork is all designed from scratch, literally from molding.Durable and ultra lightweight. Unprecedented 30 mm rake (distance between center of steerer tube and wheel center) helping riders to achieve super tight cornering.This updated frame now has enough clearance for 32c.For material, they’ve embraced the power of 7005 Columbus Airplane Aluminum, all ready to take off! Got bottle cage mounts on the down tube which is always a great addition.On the smoothly finished fork crown and rear bridge is a hidden brake mount. With or without brakes (the latter NOT allowed in Japan!!), do what you prefer!*option*We will face and tap the surface of head tube and BB. We’ll make the frame sets good to go straight out the box.We could also install headsets, BB and we can cut the steerer column for you. Let us know if you need to.
