    Hope floating rotors and Marta calipers?????????????

    Has anyone tried to use Hope floating two-piece rotors with Magura Marta calipers. I am thinking of try it. Just want to know if it works.

    Maybe.

    It depends on what caliper & what size rotor.

    I don't have any 160 mm Hope rotors so I have no idea if those will work.

    The 140 mm Hope rotor will work on the rear with a front caliper but the rivets are also very very close to hitting the caliper - dangerously close in my opinion. It is also has a very thin braking surface- only 1.7 mm vs. 2.0 mm for the stock Marta rotor.

    The 180 mm Hope rotor will not work on the front with a rear caliper. The rivets will not clear the caliper. The braking surface of this rotor is 1.8 mm - also quite thin.

    I've also found the quality control on my Martas to be not so good when it comes to machining the mounting surface. Mine vary by more than 1 mm! This means I have to add or subtract more spacers between brake sets. I expected MUCH less variation than that! All these errors add up so much that some combinations of parts simply aren't safe to use.
