I just threw some BB7s on the Cinelli I built up today, but then again Shimano hydraulics have never done anything for me.

Haha, that's what I wanted to do, since I was focused on not spending any extra money this build and didn't have any other rotors laying around. However as luck would have it I misplaced some adapters and am running the 203 in the back. It looks funny as hell.

higher end shimano hyrdos are fine (although personally i prefer avid juicys) but I believe it was the deore ones that had problems last year, many of them had some problem i'm not exactly sure what it was but they where like overfilled and then they leaked out the caliper when you squeezed the brakes, which contaminated the pads. This made them sqeek horribly, it took forever to fix the problem, and on some of them it just couldn't be fixed, shimano ran out of brakes becuase so many people needed replacements. Now many of the bikes that had the cheepo hyros last year have either bb7s or juicy 3s.

I think that was the deores, just did a google image search, feel free to correct me if it was actually a lower model (do they even make a lower hydro?)

So yeah i'd get the bb7s, or if you want hydros spring for lx or juicy 3s

How about the Hayes 9's as an option? Jenson has them for slightly more than the BB7's. I have considered them for my bike. Guys at the LBS say they are excellent once dialed in. The small adjustment screw is apparently a little tricky.

Which/what adjustment screw might that be?

They showed me, it is an allen key and is kind of up inside the housing behind the lever. It adjusts the reach. Hard to describe without a visual.

It didn't scare me too much either. Still leaning toward the Hayes 9's.

True, I got pretty good at it after having to readjust it 10+ times per ride.

I hear the newer models have addressed that issue though.

I was reading in another post that some people have addressed the loosening screw by wrapping it with some white teflon tape, or some loctite - but the loctite is messy.

I have two bikes, one runs bb's the other runs deore hydros.

If i had to choose between the two brakes for a xc or am bike I'd take the deore hydros. They've got better modulation than my bb's (perhaps because the deores are 2 piston vs the 1 on the bb's) and feel smoother than cable pull brakes ever could not to mention that they're self centering. I just feel more connected to my deores which for me translates into more confidence in the trails. I've had none of the leak issues that the others have mentioned and I've logged close to 3000 clicks on those brakes over the past year.

The bb's are good. They are super easy to dial in and have a ton of stopping power, probably a bit more than my shimanos (may be due to the sintered pads in my deores). They don't feel like budget brakes, and are a good choice but they won't feel as nice as hydros. Period.

Btw, unless you're running downhill or some serious brake burner trails there's no point to 203 rotors, they don't improve brake power, just heat dissipation. 185mm = less chance of warping = quieter brakes. I had a slightly warped 8 inch rotor on a previous bike and it annoyed the hell out of me.

If you are going 203 on the front- Get a Bolt through front axle. The strain of that size disc on a QR front fork could cause problems.

I've used some low end Shimano hydros on a friend's Cannondale F4. I have no clue about maintenance or longevity, but from the couple hours that I rode it, the power was plentiful and the lever feel was pretty decent as well.

i ride both on my mtb. bb7 in back and the hydro up front. the deore is a last generation, probably 06/07 and it works as well as the bb7 but there is less adjustment, which i think is a negative. the brake squeals a teeny but but i got it for 80 bucks attached to a xt dual control lever so its a good buy for me. id say theyre about equal.

I know it's late for this thread but I wanted to chime in. I've own and used Three sets of Deore Hydros on different bikes and for the money they are a great buy. I never had any issues with any of them. I'm still using one set of take offs that I bought in 05.
