Fork
The Grand comes factory-installed with the RST VITA fork. This has a travel range of 80mm. Bike forks are great for shock absorption and provide you with a smooth ride. In short, you should always ensure you have a good fork when purchasing a bike.
Wheels size
The wheels on Grand are the 29″ aluminum type. Having 29″ wheels means that you need less fork travel, leading to a reduction of the pedal bob effect. However, if you’re not a tall person, you might find it difficult to adapt to this wheel size.
Brakes
For your safety, it is important to have quality breaks on your bike. Author Grand 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.
