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! |
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. |
Cons
These jockey wheels do not turn as smoothly as variants with ceramic bearings. |
