    Rotor replacement

    When should I replace them? Any time frame? How do I know theyre garbage and need to be replaced?

    There's no real "time frame" for rotor replacement. General rule of thumb is, when you start to feel a difference in thickness between the braking track and the rest of the rotor, they should be replaced. If you want to get more definite, most manufacturers do have a "minimum thickness" spec for their rotors. You'll have to dig into the tech documents for your brakes or contact the manufacturer for their specific specs and recommendations. Of course if you are using aftermarket rotors then you'll have to contact the rotor manufacturer.

    Like I said, no specific time frame, it depends more on wear than time.

    It would be nice if manufacturers would indicate the min. thickness on the rotor. A few brands do, but none that I have on my bikes.

    FWIW my new-in-bag Magura rotor is .07" thick. I've seen some min. thicknesses spec'ed at .065". Which doesn't seem like much difference, but as Squash mentioned it is a difference you can easily feel.

    Seriously, I've got a 6 year old Dirty Dog front rotor that's going strong. I ride a lot!

    Mine are pretty old, I wasn't sure if the idea was the same as car brakes. Every few time you do the pads do the rotors too.

    You only have to replace rotors on a car when they're thinner than minimum thickness. Same as on a bike. There isn't any correlation between number of pad changes and rotor changes on either vehicle.

    Usually the more you change the pads the more the rotors get worn though so it would be true in theory.

    Any one know if the Magura rotors on Chainlove will work for the Formula The One brakes? The Magura rotors are 2mm thick but cant find a spec on the Formulas?
