With a geometry that's perfectly balanced for aerial antics, the Flying Circus is designed to be tough. Choose the top tube length that best suits your riding style, then use the super-short chainstays to manual to your heart's content. The dropouts are adjustable and we even fitted an integrated headset to reduce weight. With an RST Dirt fork, RaceFace Aeffect crank, hydraulic disc brakes, Schwalbe Billy Bonkers tyres and a single-speed setup, it's got everything you need to perfect your steeze.
Whether you're at the pump track or your local dirt jump hangout, the last thing you need is to be worrying about your frame. That's why, with the Flying Circus, we applied all our aluminium frame-building know-how to make a chassis that's stiff, strong and perfectly balanced. A BSA threaded bottom bracket gives you a wide choice of crank options, while the jump-specific geometry with super-short chainstays puts you firmly in control.
