If the Big Block is our dream trackie then the Dropout is our ideal bike for all around mayhem and alley exploring. However you choose to build it up: fixed brakeless, two brakes and a freewheel, coaster brakes, polo, dirt, etc. The Dropout is a platform for pretty much anything you want to do that involves 700c, large tires and hard riding. It can handle trails, jumps, errands, bars, hardcourt, messengering, whatever. It's the ultimate get around, bash around, knock around city machine. It's fast, fun, and comfortable.
The Dropout comes with all of our standard hallmarks, custom headbadge, signature dropouts with built in tensioners and thoughtful design. It also sports a machined headtube that takes a Campy 45/45 internal headset because good quality headsets are available at very reasonable prices in this standard, and BMX bikes have proven its toughness and reliability. Instead of paint this baby is ED coated for rust prevention and then powdercoated for ultimate finish durability. The 990 BMX studs are removable, as is the rear brake cable routing.
In short the Dropout is an extremely capable urban platform that can be built up in a myriad of configurations to suit your riding style and needs. There are a ton of ways to have fun on this bike.
