Rockhopper Comp Disc 29 components
Fork
The Rockhopper Comp Disc 29 comes factory-installed with the RockShox fork. This has a travel range of 80mm. Bike forks are perfect to absorb shocks and provide a great riding experience overall. To sum it all, when buying a bike, ensure that you look for a fork capable of decent travel.
Fork material
Rockhopper Comp Disc 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
The Rockhopper Comp Disc 29 2009 bike is equipped with 29″ aluminum wheels when leaving the factory. These wheels are more forgiving when you go over roots, rocks, bumps, or other obstacles you encounter on your ride. However, 29″ wheels will make your bike react slower to obstacles you may encounter.
Brakes
We ride faster and faster, so a good braking system is essential on a bike nowadays. The Rockhopper Comp Disc 29 comes with Mechanical Disc brakes. They are much easier to maintain than hydraulic disk brakes. However, performance-wise there is room for improvement.
