In the beginning, I was a bit nervous running regular dropouts w/8" rotors and emailed Marzocchi about this. They responded that the 2004 Z1 FR series forks were all rated for a 8” rotors. I've had absolutly no problems over the 2 seasons & 2000+ off road miles with this setup. (Still keeping fingers crossed however...)
BTW: All of Marzocchi’s 2005 free ride forks come standard with 20mm though axles.
