Overview of components
Fork material
When it comes to the fork, this bike has a steel one, which tends to be more flexible than carbon forks in general. However, a carbon fork is considerably lighter.
Wheels
The EXPLORER A2 2021 bike is equipped with 27.5″ aluminum wheels when leaving the factory. The 27.5″ wheels are a great choice for smaller riders. 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 EXPLORER A2 has Rim brakes. Slightly lighter than hydraulic brakes, rim brakes are a budget choice. However, they are not nearly as effective as hydraulic brakes are.
