Daryl posted that the LoK will work with galfer rotors, the only difference is that you have to roll the bike farther to seat the LoK. I think the issue with aftermarket rotors is that becuase of the different size if the diffuser holes, the bike will have more movement, but the lock is still "snapped" in and you would have to remove the rear wheel to get the LoK off of the bike with out the key...(CYCLEERIC @ Sep. 13 2006,06:10) Im wondering if this would work with my Braking Wave rotors ?
