Just in time for Christmas. JUst ordered a set today along with a pair of DT swiss centerlocking adapters. I got an 8" rotor in the front and a 7" out back. So pumped.

why the 7 in the back, those are great brakes, i love mine, i am probably gonna replace the hydros on my p.2 with the bb7s

I guess the 7 in back for a more balanced look. It sounds stupid but I like good looking stuff, but I guess just to look a little different from the front. Really no legit answer. lol

Funny. I recently gave a lecture about "consumer's rationale". Will copy and paste this thread to my PPT presentation if you dont mind.

Ricardo

ya that's fine with me. The mechanic at the shop asked why i wanted an 8 inch rotor and before i could answer my dad said "obsessive compulsion." and the mechanic said "good reason"

The front brake provides more stopping power, so there is some rational rationale for a larger front rotor.

Will a 7" rotor work on the back of a hardrock?

sure it will work.. you don't even need pads or calipers the chainstay makes great friction material.


all kidding aside I was wondering the same thing seems like most xc frames are designed for a 6 inch rotor..

Yes.

It was one of the things I have never really heard of working, so I have learned something.

well i cut out a 7" paper template to see and it fit. But we'll all find out soon enough. Well, next week

was your paper 1/8th of an inch thick?

hmmmmmm...good point. No it wasn't. But if there are any problems i can always just get a 6" rotor for the back.

So rotors are now like "Dubs" for cars? It doesn't matter if the performance is better or not, it's just for looks?

if it doesn't quite fit you could dremel a very small spot on the stays. touch up with auto paint. alternatively, smash a small spot with a hammer until the rotor clears frame.

i hope you bought spare cables.

uhhuh, correct.

hahaha very funny im not that stupid

i don't think a dented stay would be too bad.. I've seen some nasty kickstand uninstalls on the stay.. But still I wouldn't do it.

and a new aapter so instea of doping research you might end up spending 20-40 on a new rotor, and 10 on a new adapter

nooo. Do you think anyone would order brakes planning on upping the size of the rotors without buying the adapters and rotors? everything i need will come with the order. The only other thing i had to order was a pair of DT swiss center lock to 6 bolt adapters. I knew what i was doing. I know you are probably going to say "well you don't even know if the rotor will fit in the back." Well it that's the case i'll just simply put on the calipers and order a 6" rotor. But i'm pretty sure everything will be fine.

for a bigger rotor you need a different adapter, for a smaller rotor you need a shorter adapter, otherwise the wheel wont fit in, or the caliper won't reach the rotor

holy crap. How many time are you guys going to whine about rotors. What do you think is on the back right now? A 6" inch rotor!! If I had to stick to a 6" rotor for the back, there would be no need to buy a new rotor. And I don't know who or where you guys buy components from that doesn't also include the proper mounting adapter or brackets.

I'm pretty sure Te***** has it covered. Adapter looks like it's Avid part no. 00.5315.012.010, rear 51mm IS to 7" rotor.

Tell us how you like 'em after you get it all set up, T.

I just got BB7s for the front of my Trek 4300 and love it so far. Mind you I have not really used it that much, due to the foot of snow we got, but so far so good... Hope you like them too...

Why didn't you just get Avid Juicy 3's? They kick some serious a**.
