2013 Octane 1 Frame Zircus

The Zircus is a brand new alloy dirt / all round hardtail frame for 26” wheels. Designed for riders who prefer the feel of alloy
frames. More slack and stabile than the radical steel Void frame. The Zircus uses beefy AL-6061 tubes that give it a
super clean look. Behind the simple looks you can find nice tech details such as custom shaped and butted tubes (a very
strong DT near HT area with no need for an additional external gusset), a custom shaped ZS44mm headtube, custom
rounded smooth looking tubes, w/o any crazy bent tubes or wacky hydroforming shapes. Although the Zircus is a very
strong frame it weighs only 2.1kg and has a very reasonable price. What more do you need?
The BB is lowered for more stability, the top tube and chainstays are slightly longer than in the Void frame and headtube
angle is more slack. The Zircus is equipped with a standard threaded 68mm BB shell so you can easily fit your favorite
mountain bike cranks. Horizontal dropouts allow a true singlespeed setup but an optional derailleur hanger is included
with the frame.
