Overview of components

Fork

The Fox Performance Float 34 is included from the factory. It has a travel distance of 130mm. Bike forks are good shock absorbers and provide a smooth ride and a great experience. To sum up, when buying a bicycle, make sure you get a fork that is capable of delivering decent travel.

Rear Shock

From the factory, it comes with the Fox Float DPS EVOL Performance rear shock model, which has a travel of 130mm. Rear shocks give you increased comfort, control, and traction, which is important when cornering or braking. This allows you to ride faster on bumpy roads. In short, a full-suspension bike will give you the smoothest ride possible.

Wheels

The wheels on Thunderbolt Carbon 50 are the 27.5″ aluminum type. 27.5″ wheels will reach higher speeds than smaller-sized wheels. However, the 27.5″ wheels are less forgiving than the 29″ wheels.

Brakes

When you want to stop the bike in time, the brakes are vital. The Thunderbolt Carbon 50 has Hydraulic Disc brakes. These kinds of brakes are among the most popular models used on bikes. To sum up, these are ideal for anyone.

Dropper post

Every bike should have a dropper post, and this one does. Therefore, climbing or descending will be a breeze.
