Overview of components
Fork
The HELIX A1 comes factory-installed with the SunTour XCT fork. This has a travel range of 100mm. Bike forks are great for shock absorption and provide you with a smooth ride. In short, make sure you choose one with a decent fork when you purchase your dream bike.
Fork material
The fork is made out of aluminum, so there won’t be much extra weight added to the bike. However, they are not so stiff as carbon forks are.
Wheels
The wheels on HELIX A1 are the 27.5″ aluminum type. 27.5″ wheels are a mixture between 29″ wheels and 26″ wheels. However, the 27.5″ wheels are less forgiving than the 29″ wheels.
Brakes
Nothing is more important on a bike than its ability to brake properly. Jamis HELIX A1 is equipped with Hydraulic Disc brakes. Hydraulic disc brakes provide amazing stopping power, no matter what the terrain. To sum up, these are ideal for anyone.
