ive been running the mt2 on the front of my stock, i run a 203mm rotor, the brake is amazingly powerful and the lever feels comfy and with to pain whatsoever on the finger, i would reccoment this brake, you wont be disapointed, mine bedded in withing 20 minutes, just took the bike down a massive hill and kept tapping the lever going down the hill, i donme it twice and the brake was bedded in, the power is amazing
