According to the product specialist
Pros
| With new derailleur wheels, your bike will run quietly again and shift gears properly! |
| These derailleur wheels have a narrow-wide fit, so your chain stays in place very well. |
| The low-friction ceramic bearings are extremely smooth and durable. |
| As the RollerBoys are made of a hard glass fibre composite they will not wear easily. |
