Lower the saddle for more room

The Hornet Pro has an X-Fusion Manic dropper, so you can lower the saddle for a descent and raise it again for pedalling. Travel is 150 mm on Medium and 170 mm on Large and XL.

A hardtail for freeride trails

The 150 mm Marzocchi Z1 fork uses a Grip damper and 36 mm upper stanchions. The Hornet Pro frame uses a front triangle based on the Thunderbird FR design. There is no rear suspension: choose features within the bike’s intended use and your ability.

Magura MT5N four-piston hydraulic brakes use a 203 mm front and 180 mm rear Storm HC rotor. Pedals are not included, so buy a suitable pair before riding.

The rims are tubeless ready. A conversion also needs compatible tyres, rim tape, valves and sealant; check the whole setup before converting.

Check the fit

The suggested rider height is approximately 165–175 cm for Medium, 175–185 cm for Large and 185–200 cm for XL. Compare reach, standover clearance and saddle adjustment with a bike the rider knows. Check comfortable access to the controls in person.

Warranty registration

Register your purchase to activate the stated two-year manufacturer’s warranty, following the terms supplied with your bike. Keep the purchase receipt and the receipt for the initial professional service.

If a claim is accepted and the original product or part is unavailable, the manufacturer or seller may provide an equivalent replacement. Its appearance or construction may differ, while its functional specification remains suitable for the original intended use. This does not affect your statutory consumer rights.

Safety while riding

Riding, falls and impacts put loads through the bike and 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.
