I just stuck some 8 inch rotors on my NRS. They sure look big and intimidating (I had 6 inches on before). The reason I switched over because sometimes on decent it seems like my brakes arent grabbing that well. At a certain point the rear brakes starts to squeal. I do mostly downhill and uphill...nothing extreme. I weight about 170lbs btw. Should I stay with the 6 inches or go with the 8 inches. Oh my brakes are mechanical Avids.
Are 8 inch rotors on a NRS too much?

Yes, 8" rotors are too big for an NRS. The NRS is a cross country bike, and as such wasn't designed for DH-level brakes. Also, your fork's warranty is probably void with that big rotor, XC forks with QR dropouts should not be used with 8" rotors.2002NRS said:

No worries, here to help.2002NRS said:
For what it's worth, I think an 8" rear rotor is overkill on anything but a DH bike. You really need a lot more rubber than with a 6" to transfer the extra force to the ground. A lot of rear travel helps too.
Honestly, I think an 8" front rotor (on an approved fork of course!) is about all you need on a bike like the VT, should be pretty good actually.
Nice bike!

Nice looking bike! But the 8" rotors are overkill. Unless you and the bike far exceed the 200 lbs. of total weight that you currently have, you dont need (or want?) that kind of stopping power. It would result in the wheels breaking free of the ground into a skid...OR...you'd be singing soprano from now on.

6 inch rotors are plenty
Take your bike to a shop and have your brakes checked out. If you have an old-school brake system that is not performing properly you might want to think about upgrading.

If a 6 inch rotor isn't stopping you adequately, then the rotors are NOT your problem -- the problem is with your brake system in general. Any XC-oriented disc brake system (Hayes, Magura, Avid, etc) will stop a 170lb person on an NRS with NO problem. I have friends who weight 50 pounds more than you on Heckler's that ride 6 inch rotors and have plenty of stopping power.2002NRS said:

I'm about 180 or so pounds and my 6" Avids have more than enough power to stop me on my Rainier. It's awesome having all that power under one finger.

Come clean. Was the upgrade for cool points or were 6's really not doing it for you?2002NRS said:
I can't imagine 6's not being enough hehe.Well, how about some 7" on the front with a standard 6" on the back? I weigh (only?) 150 lbs. and I had some 6" Hope Mini's fade on me. Kinda scary when you are approaching a giant pine tree at 30+ miles per hour. Well, at least, it felt like 30+ miles per hour. You mentioned that you were using Avid mechanicals. I have Avid Juicy 7's. Just buy the 7" bracket with some rotors and you should be good to go. Those 8" rotors do look a bit funky. They look almost big as your wheels!
At first I got the 8's because man they sure look cooldissonance said:Come clean. Was the upgrade for cool points or were 6's really not doing it for you?
and I wanted to get these
After I going back to the 6... its not the same anymore. I really like the stopping power of the 8.
RZK: I might just try out the 7's since I just sold the 8's

I've got a 180mm (approx. 7") front rotor and 160mm rear rotor w/ Mono Minis and I love them. Anything bigger will void the warranty on pre05 Fox forx anyway. In the rear you really don't need a huge rotor at all- it will just make it way too easy to lock it up, which you want to avoid. I actually prefer the modulation of smaller rotors in the rear for riding wheelies and manuals. If you want some rotors for style points, get some Hope Gothic rotors.
