A larger front wheel, a more compact rear

The Hornet Mullet uses a 29-inch front wheel and a 27.5-inch rear. The front rolls over uneven ground, while the smaller rear wheel keeps the back of the bike more compact. Tyre sizes differ too: 29 x 2.6 inches at the front and 27.5 x 2.8 inches at the rear.

One shifter and a clutch derailleur

The 32T chainring and 11–42T cassette give you nine ratios for changing gradients. The Advent derailleur’s clutch helps manage chain movement over rough ground. You use one shifter, without a front derailleur to operate.

The X-Fusion Trace 36 RC fork has 150 mm of travel. Shimano MT410 two-piston hydraulic brakes use a 203 mm front and 180 mm rear rotor. Check their adjustment before riding, and choose enduro trails or bikepark features within the bike’s intended use and your ability.

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 160–170 cm for Small, 170–180 cm for Medium and 180–190 cm for Large and 190–200 cm for XL. Compare reach, standover clearance and saddle adjustment with a bike the rider knows. Check comfortable access to the controls in person.

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.
