RFX Aluminum transmission chainring PRO SERIES ARMALITE - 520 1123236012

RFX Pro Series Armalite Crowns are designed and tested to the highest level by the best British and World Championship racing teams.

The double ring design provides maximum crown performance, low weight thanks to the 7075-T6 aluminum center and long tooth life thanks to the high carbon steel exterior.

Armalite crowns also incorporate a hex drive interface between the inner and outer ring, a revolutionary technology that maximizes drive between the two parts and reduces force on rivets to zero, unlike the competition.
