what size rear rotor on an All Mtn bike do you run?

I run 200mm Avid HS1 rotors front and rear but my bike is a little more oriented to bombing down hills. I'm on a Specialized Enduro Expert Evo (2012) and I'm running Code calipers front and rear. I weigh about 220, so that factors into my rotor size choice.

Its crazy but I run 203mm on all my bikes. I do this so I always have back up rotors if I bend one and need to steal from another bike

I tend to keep the rear smaller. Six inches on a trail bike and seven on the DH. All the power is from the front brake, the rear is just to keep you straight.

185mm front and rear.

i still use 160mm rotors (front and rear) on my bike.

considering to change to 180mm up front.


Edit: Now i'm using 180mm front and rear. I really felt the difference. Braking is much, much better.

203mm front & 180mm back.
I am kind of big, so I need the extra size to slow me down..

Update: I'm on a Yeti SB-95 (95c frame on order, should be here any day) now. Still running same 200 front and rear but considering dropping the rear to 180.

Usually dual 180mm rotors.

203f 180r I'm a big dude tho, 250lbs

203 upfront and 180 rear
