I've got a Reign 2 with Hayes nine disc brakes and a six inch rotor on the front. Should I put a bigger one on and if so would you recommend 180mm or 205mm. Do I have to get a Hayes one or can I use Alligater, YD Open or Shimano? I don't want to go overkill but is there any noticeable difference between going biggerl? I have a Manitou Nixon Elite fork. I guess I need some sort of adaptor, post mount?? and how would you describe it. What is required to fit a bigger rotor. I don't know the first thing about it. I asked my local LBS who I had just bought my bike off and they weren't helpful, probably cause I meantioned I could get a rotor for half their quoted price, but they said I shouldn't need a bigger one, it was big enough. Last time I was descending a steep downhill (rather slowly) for some distance, I could smell my brakes burning and I was still moving.They still worked but didn't fade (I don't think, but then I'm not pro enough to tell), but they also weren't able to lock the wheel up either and I had to pull pretty hard.
