Lower the saddle before the descent

The X-Fusion Manic dropper lets you lower the saddle for more room to move above the bike, then raise it for pedalling. Listed travel is 125 mm on Small, 150 mm on Medium and 170 mm on Large and XL. Check the post’s position and operation as part of the bike’s setup.

Set the fork for your weight

The X-Fusion RC32 Boost Air fork has 130 mm of travel, with compression and rebound adjustment. Set the air spring and damping according to its instructions and your weight. Use a suitable shock pump and observe the permitted pressure range.

Ten gears, one shifter

A 30T chainring works with an 11–48T cassette, giving you a choice of ratios for changes in gradient. The Advent X derailleur has a clutch to help manage chain movement over rough ground. There is no front derailleur to operate.

Shimano MT-400 two-piston hydraulic brakes use 180 mm rotors. Have them adjusted and test their operation before every ride. Raptor rims carry Crown Gem 29 x 2.3-inch tyres. The rims are tubeless ready; a conversion also needs compatible tyres, tape, valves and sealant.

Compare the frame sizes

The suggested rider height is approximately 160–170 cm for Small, 170–180 cm for Medium, 180–190 cm for Large and 190–200 cm for XL. Compare reach, clearance and your preferred riding position with a bike you know. Height alone does not determine fit.

A 780 mm Tornado Low bar, short Viper stem and railed Ferns saddle complete the contact points. The listed weight is approximately 14.70 kg. Choose routes within the bike’s intended use and your ability, and inspect the bike after hard impacts.

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.
