Rockhopper Sport 29 components
Fork
The SunTour XCM is included from the factory. It has a travel distance of 100mm. Bike forks are great for shock absorption and provide you with a smooth ride. To sum up, when buying a bicycle, make sure you get a fork that is capable of delivering decent travel.
Fork material
Rockhopper Sport 29 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.
Wheels
When leaving the production line, the Rockhopper Sport 29 model has 29″ aluminum wheels. Having 29″ wheels means that you need less fork travel, leading to a reduction of the pedal bob effect. However, these wheels are not ideal for smaller people.
Brakes
For your safety, it is important to have quality breaks on your bike. Specialized Rockhopper Sport 29 has Hydraulic Disc brakes installed. With Hydraulic Disc brakes, you’ll be able to stop on a dime, even in wet or icy conditions. To sum up, these are ideal for anyone.
