Octane One Zircus 26" Frame

Octane One

299.00 $ 349.99


The Zircus is an aluminium all-around dirt frame perfect for playing in the city and off-road. It’s a lightweight and strong aluminium frame set with ‘Pro’ dirt-jump geometry designed to fit 26” wheels, forks with 80-140mm travel and a single speed drive-train; however the frame includes a removable derailleur hanger so you can convert the bike into a serious all-purpose off-road machine with gears (if needed).

Designed for riders who prefer the feel of aluminum frames, more slack and stability than the radical steel Void frame. The BB is lowered for more stability, the top tube and chain stays are slightly longer than those in the Void and the head tube angle has more slack. Tough enough for jumps, perfect for pump-tracks, and comfortable enough for trail riding.

The Zircus uses beefy AL-6061 tubes that give it a super clean look. Behind its clean look you can find awesome 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 new custom shaped fully integrated tapered head tube, custom rounded smooth looking tubes and a sweet arched seat stay bridge that gives tons of tire clearance.

The Zircus frame is all you will need to rip like a pro in any terrain! For such a strong frame, the Zircus only weighs only 2.1kg and is offered at a very reasonable price!
