You can tune the fork to your weight and riding using the instructions for the fitted fork. Lockout is also available; follow the fork guidance when choosing a setting.

Floval tubing and a single-speed build

The 6061-T6 aluminium frame uses hydroformed, butted Floval tubing and a Looptail rear end. Chain tensioners help you set the rear wheel position when adjusting chain tension. The drivetrain has one gear and a 12T driver, so there are no gear changes to manage on a session.

The 26-inch wheels use double-wall, 35 mm-wide aluminium rims and sealed-bearing hubs. Vee Tire Co Two Six DJ tyres measure 2.25 inches at the front and 2.125 inches at the rear. The SE V-Ridge cranks have 175 mm chromoly arms.

Check the fit and brake setup

The suggested rider height starts at around 160 cm. Compare your reach and frame clearance with a dirt jump bike you know. The bar is 736 mm wide with a 63 mm rise, fitted to a 40 mm front-load stem. The Pivotal saddle allows angle adjustment within the system’s limits.

Tektro HD-M285 hydraulic disc brakes use 160 mm rotors. Have the brakes adjusted, check the controls are within comfortable reach and test them before riding. Choose jumps and features that suit your ability.

Safety while riding

Dirt jumps, tricks and landings put high loads through the bike. Falls and impacts can damage components. No bike is indestructible: parts can wear out or become damaged. Check the frame, fork, bars, wheels, axles, cranks, pedals, brakes and bolted connections before every ride. Inspect the bike after a hard impact and stop riding if you find looseness, cracks or damage. Have any problem checked and repaired before riding again.

Wear a properly fitted helmet and suitable protective pads. Read our important information before buying and using a bike for assembly, servicing and riding checks.
