Upgrading Brakes
hey all,
I have a 2007 Specialized Hardrock Sport Disc. After using it for a while, I have discovered that the brakes aren't powerful enough, especially in Seattle, where it's very hilly.
I have done some research and decided to upgrade to Avid BB7 brakes. However, I have some questions.
Will the brake fit on my fork? (RST Gila Plus t7) The RST site gives no info on the disc mount hardware
Will the rotor be compatible? I currently have Shimano 415, which uses Centerlock to attach the rotor.
If the answer any of the above questions is no, is there anyway to get around it?
And also, if it is possible to install a BB7 system at all, can I move up to a larger rotor? I currently have 6 inch rotors, the BB7 comes in 160,185, and 203 mm sizes.

hey i have the same bike
i think those brakes stop on a dime but thats ust me.
for me im more worried about a better fork before i do any brake upgrading, you might also want to consider fork upgrades

Really? I find the Shimano brakes not good enough. I'm a 200 lbs guy and I bike in Seattle, where its hilly. I don't like the fork either but it works I suppose. I'm more concerned with my stopping power at the moment

if you have a centerlock hub, it'll only accept a centerlock rotor, from shimano right? you can get a part to convert, but i hear its expensive. bb7's aren't centerlock, they're 6bolts.
someone correct me if i'm wrong.

Yeah the calipers don't care if they grab a centerlock or 6 bolt rotor.

You guys are right, the rotor is a centerlock. While I could use the shimano rotors with the Avid calipers, I have been told its never good to mix. Also, some people say that the shimano rotors have a thinner braking path than other rotors (and the calipers that com with). This adapter that was mentioned... how much would it be?

I upgraded my front rotor to 8 inch as I found my 6" lacking as I prefer one-finger breaking and I wanted quicker response. I outfitted my wife's bike with wheels with centerlock hubs, but prefer Avid mechanical brakes. I bought the DT Swiss (I think that's the brand) locking ring (from Performance) which allows you to use any rotor on the Shimano hubs.
The cheapest way to go is keep your brakes and go to a larger rotor. I would imagine all forks meet the international standard and you can put any brake on it.

It isn't bad to mix. Heck I rode for 2 seasons with a Hope rotor and a Hayes caliper. It's not a big deal. But yes you might want to see if they are the same thickness at least. Sorry can't help you with that.

Also here is a cheaper centerlock adaptor from the same store, before you ask..... I'm assuming this one uses the lock ring that you alreday have. A quick call to their sales dept would verify or deny that.

Okay new question. After carefulo visual examination of the bike, I see 6 silver bolts around the rotor. Is it possible that though the hub is centerlock that the rotor isn't and Specialized used an adaptor to fit the rotor on?

Yep it's centerlock, The avid brakes will bolt on just like the ones you have now. You can use the centerlock rotors you have no problem,unless you want to go bigger.
