Overview of components
Fork material
Roll – Low Entry has a steel fork, so, it can add some extra weight to your bike. However, steel is a pretty tough and durable material.
Wheels size
The Roll – Low Entry 2018 bike is equipped with aluminum wheels when leaving the factory. 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
For your safety, it is important to have quality breaks on your bike. Specialized Roll – Low Entry has Rim brakes installed. Slightly lighter than hydraulic brakes, rim brakes are a budget choice. However, they are not nearly as effective as hydraulic brakes are.
