Octane One Zircus Frame

The Zircus is an alloy allround dirt frame perfect for playing in the city and offroad. It’s a lightweight and strong aluminium frameset with ‘Pro’ dirtjump geometry designed to fit 26” wheels, forks with 80 - 140mm travel and a single speed drivetrain. However the frame includes a removable derailleur hanger so you can convert the bike into serious all - purpose offroad machine with gears if needed. Designed for riders who prefer the feel of alloy frames. More slack and stable than the radical steel Void frame. The BB is lowered for more stability, the top tube and chainstays are slightly longer than those in the Void and the headtube angle is more slack. Tough enough for jumps, perfect for pumptracks, comfortable enough for trail riding.
The Zircus uses beefy AL6061 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 and sweet arched seat stays bridge that give lot’s of tyre clearance.
This frame is all that you will need to rip like a pro in any terrain. Although the Zircus is a very strong frame it's affordable and weighs in at only 2.1kg.
