I'm thinking of changing my original Tektro Polygon rotors to Shimano RT66 rotors. Both use 6 bolts and 160mm size. Is this will be fine with my Tektro Auriga brakes? And will changing the rotors cause significant difference?

  • What do you mean? I'm pretty sure if the rotors are in the same size it'll be fine. What I really wanna know is will this make a significant differences on brakings. I just wanna know so I won't spend it for nothing. Commented Jul 1, 2015 at 0:45
  • Sorry, there was a useful comment above mine which was better as an answer.

You'll just have to make sure that the rotors match the type of brake pads you use. Shimano mark their rotors for 'resin pads only' and the like! –

  • RT66 rotors are compatible with metal ceramic pads that Tektro use. Commented Jul 1, 2015 at 0:46

    There should be no problem then. Make sure to tighten the screws on the rotor to the right specification (use a torque wrench!) and re-check after a short ride.
