avid BB7 or hydraulic disc???

i want a new front disc and am not sure wether to get the new avid ball bearing 7 or a hydraulic disc brake?
reviews say that the avid is easier than a hydraulic and just as powerful. also, im not a mechanic to say the least so d have to bear tht in mind.

I'm gunning for BB7s myself. I've heard they are very good brakes. I think the reason why mechanical discs have such a bad rep is because they install the cheapest of the cheaps on low end hardtails and those really do suck.

You may have slightly better performance on some high end hydros, but is that worth spending more than double the price you would on BB7's? Also, I'm fond of the whole not having goo in my brakelines thing, should (God forbid) anything go wrong on the trail.

That said, my experience with disc brakes goes as far as some really cheap "Winzip" (generic) discs on my old beater bike and a few test rides with nicer ones. I'm just relaying what I've gathered from research on this subject. I'll probably be rocking some BB7s in a couple months once my bank account recharges from "new bike shock."

Depends on what hydro you are comparing the bb7 to. I am assuming if it is price range to price range the comparisson is to low end hayes etc. If thats your pricepoint, get the bb7's.

Otherwise if you are just trying to cheap out but have the 3 to 4 hundred bucks to spend, hydros are better.

Go with the bb7's

Definately go with the bb7s because i just got a set of the 160mm and i've had them for about a week and they are pretty much broken in. They stop very well but are pretty noisy brakes but it seems like all avids are. Also my friend has juicy 5's and they stop very well and he hasnt had any problems with them. So pretty much bottom line i would go with a bb7 but with a bigger disc and they will stop even better.

It all depends on what you ride. But if you had rim brake before, then I suggest you just get BB7. You don't even need a new lever. Hydraulics has its good points but its a pain to setup sometimes and you might have to bleed it too. It doesn't give more stopping power but it will add weight to it.

jesus h christ. Why do people think its so hard to set up. Almost all systems come preblead so you literally have to remove grip and shifter, put on level, put on shifter (maybe reversed depends on your preferred setup) put on brake, zip tie appropriately, centre caliper and done.

Bleeding takes less time (for me anyways) then doing the yearl replace relubing of cables and lines. With hayes it takes about 3 minutes. I haven't had to redo my avids yet, in two years

Not more power...I won't even cover this one, thats just dumbass bull****.

Also to take full advantage of the bb7's "modulation" you need the matching lever. Yes, a standard lever will work, but you won't get that special warm feeling like touching a hydro brake

and yes, I own both types several times over. Hayes, hayes 9's, bb5's, bb7's and avid juicy 5's.

I had bikes with hydraulic but now run BB7 in all bikes. Hydraulics do have a better feel, even cheap hydraulics as Deore or Hayes that compete in price with BB7s. The nice thing about BB7s is that you never have pads rubbing the rotor and you can definitely fix anything that might go wrong. In my case having the same brakes in all bikes makes maintenance easier and more efficient. BB7s are a good brake to standardize when you have more than one bike.

I dunno about easier, it's mostly a matter of reading the instructions and noting the differences between brands and models.

But having the same brake on every bike does have the advantage of allowing part swapping if you're in a pinch... brake components, wheelsets, etc.

not really reading anyone elses posts... but i got some bb7s. had some trouble getting them to work on my hub, i bought an adapter and after they got broken in, well now to say the least they are amazing. they give the mechanic feel that no hydrolic break can give, yet you can stop on a dime and do all the endos you want

I will post the best advice so far in this thread:

Get the "BB7" because the name is easier to spell than "hydraulic".

i used to run bb7 but now i have juicy 5s i got cheep on ebay, they don't seem much more powerful, but i really like the feel alot better, i feel like i have more control, and more modulation, but if it was me the biggest thing would be that i wouldn't want 1 mech and 1 hydrolic the feel is just way to different, but i really love my juicys

It all depends on your needs. I raced DH on 8" BB7s last year and they were a vast improvement over what I'd had before. But I made the switch to hydros this year (Hayes Mag HDs) and I really felt that difference too. For racing, I won't go back to mechanicals. But I wouldn't rule out putting them on a trail bike.

http://www.spadout.com/store.php?stpr_id=8068

http://www.spadout.com/store.php?stpr_id=8070

the 1st link states Avid ball bearing disc brake, while the 2nd states Avid BB7 mechanical disc.. whats the difference?.. i went to the SRAM site and didn't see the 'Avid ball bearing' model listed...

avid cable operated are not as powerful as high-end hydraulics, BUT

they are very damn powerful and are easy to maintain and setup and all that.
and...no goop


but hydros are the king of super-sensitive 'barely touch them and full lock'
but you don't need brakes -that- nasty sensitive unless you simply prefer it


avid 'BB' stand for ball bearing...could be the same brake

I have to push for some hydraulic Hayes 9's. Mine are quiet, sticky and smooth to operate.

And for what its worth, their customer service is really good too.
