Rockhopper Comp Disc 29 components
Fork
This bike has the RockShox fork installed. The fork’s travel is 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
The fork is made out of aluminum, which is a lighter material. However, it is not as tough, nor durable as steel is.
Wheels size
When it comes to wheels, the Rockhopper Comp Disc 29 bike is equipped with the 29″ aluminum model. 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
Nothing is more important on a bike than its ability to brake properly. Specialized Rockhopper Comp Disc 29 is equipped with Mechanical Disc brakes. They are much easier to maintain than hydraulic disk brakes. However, with hydraulic disk brakes, you have the ultimate braking power!
