Dropout Limited Edition
Just like the regular Dropout but without the brake capabilities. This is a one time deal with only 130 being produced.
Features
Frame: 100% full 4130 ChroMoly steel. Double butted down, top, and seat tubes. Top and down tube gussets at the head tube.
Fork: Fully Heat treated 4130 ChroMoly tapered fork blades and steerer tube, custom fork ends with integrated lawyer tabs.
Internal Headset: Campy 45/45. It’s hard to argue with any standard with the word “Campy” in it.
Signature Dropouts: 4130 investment cast AC signature dropouts featuring built in tensioners.
Steel tubing: Steel is the only choice for a bike that you can ride all day and beat the crap out of in total comfort.
Freestyle Geometry: A hyrbid of track, BMX, and mountain which is comfortable enough to ride all day, gives plenty of bar spin clearance, minimal toe overlap, and provides a nice platform for bunny hops. It sliders like a dream, and puts smiles on children’s faces.
Tire clearance: 38c’s in the frame with the wheel slammed all the way forward in the dropout (pull it back for more clearance), 47c’s in the fork
