FBM’s classic CB4K’s are back and updated for today’s riding.
They feature a one piece CNC machined steerer tube, Roasted heat treated internally butted legs, Roasted heat treated 3/16″ laser cut dropouts that are angled at the bottom for grind clearance, a compression bolt that accepts a 3/8″ drive ratchet for easy installation and removal, and clearance for 2.35″ tires.
Like FBM’s frames, they’re handcrafted FBM in NY.
They can be ordered online from Last Call here.
Complete specs are available on the FBM site.
