Roll – 2018 components
Fork material
The fork is made out of steel, which is tougher than carbon in the case of an impact. However, it can add some extra weight to the bike.
Wheels size
When leaving the production line, the Roll – 2018 model has aluminum wheels. The 650b wheels are very similar to 700c, with a slight difference in diameter. 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. Specialized Roll – 2018 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.
Sizes
Roll – 2018 comes in 3 sizes, that range from 158 cm – 187 cm (5.18 ft – 6.14 ft). In conclusion, finding one for you shouldn’t be a problem.
