    180MM Rotor Options

    Looking for some advice on 180mm Rotor Options. I'm a 215 lb rider riding aggressive XC. I've got Tektro Draco brakes (may replace at some point) with 160 mm stock.

    I recently upgraded to 180mm Avid HS1 along with a pad change and seating. Started with great stopping power, but I cannot get over the noise. I've cleaned them 3 times in the week I've had them on. The longest they have lasted was about an hour before ear splitting screech on both. By the end of a 5 hour ride I was ready to throw my bike.

    Just switched back to the stock rotor, near silent now. I really like the added power with the 180's but I don't want to piss off every other trail go'er. Any suggestions on other rotors?

    Shimano SLX RT66 rotors, bought a set 180/160 at REI for less then $60. They work a lot better then my CleanSweep g3's (paired with Shimano m596 brakes so that may be why).

    Consider the Ashima Airotors. Mine stay quiet, even though I only use Avid brakes, which are supposed to be noisy no matter what.

    My go-to rotors are Magura Storms. Never a problem, and they seem to solve the noise problems.

    As you will soon find out it's all trial n error with various brands, sizes etc. The harmonics of braking systems on certain frame material is a key factor in noise reduction. The same brake components can be used on a steel frame and be awesome, yet used on alum and squeal like a 3 headed chicken.........but then used on carbon with only a hint of squeal. Take the same brake setup but use a 180mm rotor and the reverse may show.

    Another vote for the Ashima Airotors, I've put these on two bikes running Avid Elixir's (XO and CR). They eliminated the squealing and also seem to help brake modulation for me.
