Demo 8 II components
Fork
The RockShox BoXXer is included from the factory. It has a travel distance of 200mm. Bike forks are great for shock absorption and provide you with a smooth ride. In short, you should always ensure you have a good fork when purchasing a bike.
Fork material
Demo 8 II has an aluminum fork, which doesn’t add too much extra weight to the bike. However, it is not so stiff as steel or carbon forks are.
Rear Shock
From the factory, it comes with the Custom Öhlins TTX22M rear shock model, which has a travel of 200mm. Rear shocks give you increased comfort, control, and traction, which is important when cornering or braking. This allows you to ride faster on bumpy roads. In short, if you want smooth rides, get a full-suspension bicycle.
Wheels
When it comes to wheels, the Demo 8 II bike is equipped with the 27.5″ aluminum model. 27.5″ wheels will reach higher speeds than smaller-sized wheels. However, the 27.5″ wheels are less forgiving than the 29″ wheels.
Brakes
Stopping the bike when needed, it’s essential for your safety. This bike has Hydraulic Disc brakes. With Hydraulic Disc brakes, you’ll be able to stop on a dime, even in wet or icy conditions. To sum up, your safety is in good hands.
