The Hawk rotor can be found used for a reasonable price.
Well worth the expense in performance upgrade.
I fitted the Lenac adapter to mine and it has improved the braking mucho!
I'm not sure if they are still available but there might be another manufacturer that sells them....someone on here should be able to advise.....
