Overview of components
Fork

Fork material
When it comes to the fork, this bike has an aluminum one, 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
The Demo 8 II Alloy has a rear shock with a travel of 200mm. The model Custom Öhlins TTX is the one installed in this bike. Bike rear shocks are a great way to increase comfort on the bike and give you more control when riding on technical trails. In short, a full-suspension bike will give you the smoothest ride possible.
Wheels
The Demo 8 II Alloy 2017 bike is equipped with 27.5″ aluminum wheels when leaving the factory. The 27.5″ wheels are a great choice for smaller riders. However, these wheels have a slower top speed if you compare them to 29″ wheels.
Brakes
We ride faster and faster, so a good braking system is essential on a bike nowadays. The Demo 8 II Alloy comes with 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.
