Xray RX8 optional brake disk adapter
For serious racers concentrating on weight savings, Xray’s new optional RX8 brake disk adapter is CNC-machined from tough 7076 T6 aluminium and has been strategically lightened compared to the standard adapter. Rotating mass is reduced without sacrificing strength or durability. Includes factory-pressed pins which are non-replaceable.
