According to the product specialist
Pros
| Because of the sealed bearings, these jockey wheels last longer, even in bad weather conditions. |
| Manufactured from 7076 T6 aluminium, these AluBoys are very light and stiff! |
| With new derailleur wheels, your bike will run quietly again and shift gears properly! |
| 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. |
Cons
| These jockey wheels do not turn as smoothly as variants with ceramic bearings. |
