ZIRCUS

The Zircus is perfect for playing in the city and off-road. With a lightweight and strong aluminium frameset, 100mm travel fork, single speed drivetrain with horizontal dropouts the bike is all that you will need to shred your local trails. A derailleur hanger is included so you can convert this bike from single speed to gears if needed. The custom aluminium frame with geometry influenced by our pro dirt jumpers combined with a selection of NS Bikes components and a great price makes this package is hard to beat.

With great rider feedback, the Octane One Zircus will be continued into 2014 under the NS Bikes brand. A number of upgrades are associated with this change, such as a full NS Bikes cockpit which includes the brand new NS Bikes Quantum stem.
