Pedal to the start, lower the saddle for the descent

The X-Fusion Manic LC dropper lets you raise the saddle for pedalling and lower it when you need more room to move above the bike. Listed travel is 125 mm (Small) / 150 mm (Medium). Check your saddle-height range as part of the setup.

Suspension for roots and rough ground

The Manitou Mezzer Expert fork works with a RockShox Deluxe Select rear shock. You get 160 mm of fork travel and 160 mm of rear frame travel. These are wheel-travel figures; the shock’s 205 x 65 mm size is a separate measurement.

For enduro trails and bikepark riding, have the suspension set for your weight according to its instructions, and choose routes within the bike’s intended use and your ability.

One shifter for changing gradients

The 32T chainring and 11–50T cassette give you a choice of ratios for climbs and faster sections. You use a single shifter, with no front derailleur to operate.

SRAM DB4 four-piston hydraulic disc brakes let you control front and rear braking separately. Have the levers and calipers adjusted and test their operation before riding.

A larger front wheel and a smaller rear

The mullet setup uses a 29-inch front wheel to roll over uneven ground, with a smaller 27.5-inch rear wheel that keeps the back of the bike more compact. Check the front and rear tyre sizes separately when buying replacements.

The rims are tubeless ready. A conversion needs compatible tyres, the required tape, valves and sealant; check the compatibility of the complete setup before converting.

Find the position that fits you

Suggested rider heights are approximately 160–175 cm for Small and 170–185 cm for Medium. Compare reach, standover clearance and saddle adjustment with a bike you ride comfortably. Height alone does not determine the right size.

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.
