Boss 7 STEP-OVER components
Fork material
The fork is made out of steel, so, it can add some extra weight to your bike. However, steel is a pretty tough and durable material.
Wheels size
When leaving the production line, the Boss 7 STEP-OVER model has 26″ aluminum wheels. The 26″ wheels are lighter than the 27.5 or 29″ wheels. However, they are less forgiving when riding over obstacles such as bumps and roots.
Brakes
Nothing is more important on a bike than its ability to brake properly. Jamis Boss 7 STEP-OVER is equipped with Rim brakes. Rim brakes are cheaper than hydraulic brakes, and also easier to maintain. However, they are not nearly as effective as hydraulic brakes are.
