Can somebody tell me either new alu belt pulleys or original are lighter and lower rotating mass
Are the effects of the alu belt pulleys significant on rotating mass
Thank you.

The pulleys are a tab bit heavier compared to the composites. But they are far lighter than the aftermarket CSO, KM or Atomic. The main reason to use the aluminum pulleys is the self-cleaning holes. The pressure of the belt will force all the dirt/rubber out of the pulley through those holes. I owned the CSO pulleys before switching to the XRAY's. The CSO pulleys are heavier, and the wear on the teeth is higher compared to the XRAY's. I have run the pulleys for a few months and after cleaning them with a tooth brush, they practically look like new. Hope this helps. |

The 20t aluminium brake pulley is lighter (about 1g) than the composite+aluminium brake pulley holder  ..this is the only one that I use. |

Usually aluminium is always heavier than plastic...nevertheless it will always offer more reliability and durability. |
