Overview of components
Fork
The Fox Rhythm Float 36 is included from the factory. It has a travel distance of 160mm. 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.
Rear Shock
From the factory, it comes with the Fox Float X Performance rear shock model, which has a travel of 150mm. Bike rear shocks increase the riding comfort, and also give you more control over technical trails. To sum up, always consider getting a bike that has a rear shock as well.
Wheels
When leaving the production line, the Sentinel Alloy NX 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, 29″ wheels will make your bike react slower to obstacles you may encounter.
Brakes
When you want to stop the bike in time, the brakes are vital. The Sentinel Alloy NX has Hydraulic Disc brakes. Hydraulic disc brakes provide amazing stopping power, no matter what the terrain. To sum up, these are ideal for anyone.
