Overview of components
Fork material
EXPLORER A2 STEP-THRU has a steel fork, which tends to be more flexible than carbon forks in general. However, a carbon fork is considerably lighter.
Wheels size
When leaving the production line, the EXPLORER A2 STEP-THRU model has aluminum wheels. After 700c wheels, 650b is the second most popular choice for road bikes. However, they don’t perform so well when you go over bumps and obstacles.
Brakes
Nothing is more important on a bike than its ability to brake properly. Jamis EXPLORER A2 STEP-THRU is equipped with Rim brakes. Slightly lighter than hydraulic brakes, rim brakes are a budget choice. However, they have problems in wet conditions.
