    Rotor options for Shimano XT disc brakes ?

    I was wondering what options I have for rotors (160 or possilby even 140) on my XT disc brakes? I am looking for something that is lightweight with good stopping power. Would the Avid G3's work? They look to be quite light.

    I appreciate your thoughts and opinions

    The lightest rotors (outside of exotic rotors) I know of which should have great stopping power with Shimano brakes would be Formula R1 rotors claimed 89g in 160mm:

    If you want to be cheap, and light, another decent choice is the Alligator Serration. I have these on my XC bike, and they have adequate stopping power, they are verified 92g in 160mm.

    The Avid G3 will work fine as well, they are verified 105g in 160mm.

    The shimano RT76 rotors are quite good. Great stopping power and stiff, they look bling too, but they are not any lighter than the standard Shimano rotors, they are verified 125g in 160mm, I got these in 203mm, 180mm on my DH bike.

    I'll be running AiRotors w/ my brakes when they show up next week. Going to be 180s on the front and 160s on the rear. Looking forward to that hydro modulation!

    If you are on a budget I would recommend KCNC-rotors. 160mm and just 82g. Very light.
