According to the product specialist
Pros
-
As the RollerBoys are made of a hard glassfibre composite, they don't wear easily. |
The BDP-05 come with bushings to make these pulleys compatible with many older SRAM derailleurs! |
The BDP-05 RollerBoys have a special internal lubrication system. |
-
Cons
-
These jockey wheels turn less smoothly than ceramic variants from the higher price segment. |
These pulleys are not compatible with Campagnolo or Shimano derailleurs. |
