What else is there on BF besides attitude?

If you're looking for substance you're barking up the wrong friggin tree here big boy.

Not all brakes are created equal.

That is all.

I got them on a bike that I bought used coupled to Ultegra brifters. My other road bike has Ultegra brakes with Ultegra brifters. I have Kool-Stop black pads on the ZG's and Shimano pads on the Ultegras. The ZG's work better, but probably due to the pads more than anything else. There is certainly no lack of stopping power with either setup.

Road Rash

I take offense to the being called ugly, red and blotcy (sic)

I mis-spelled botchy.

i would say that the calipers in question were indeed not installed correctly, as correctly installed calipers cannot be easily knocked out of alignment to the point of needing a tool (a cone wrench) to realign them.

correctly mounted, ZGs are just as solidly "centered"* as any standard set of calipers.

* "centered"=not exactly centered, as is the correct way to mount ZG calipers

Cycling news had a similar review vs. Pez. I never heard anything bad about zero G before reading this. Kinda thought of them as one of the few weight weenie gadgets that still works.

Looks like earlier versions were no so good, last 2 years better?

If you were at the level where those few grams would make a difference, you would already know the answer.

Don't be pissing on the Weight Weenie Parade.

That's my job.

My MotoB Fly Ti Hardtail will be lighter than all your Wussy MTB's anyway. In fact it will be lighter than some of the sub-Fred road bikes here. What is a 'sub-Fred'? That's a whole other thread.

WTF is this MTB thing you refer to? I can only assume that you have resorted to heavy drug use. Most likely to ease your glaucoma, arthritis, or other age induced malady.

BTW - you are late for your carbon injection patient PCad. Hopefully your medicaid can cover it this time.

Actually they were install just as ciamillo recommends but when you throw a wheel in and hit the pad they will come off center and they do need to be realigned. As a weight weenie who is surrounded by other weight weenies this wasn't my first set and not the only set I have seen.

People have always complained about the performance, I don't think the complaints have gotten any worse. Mine stopped me just fine for over a million feet of descent last year, so... whatever. Are they better than Dura-Ace? Dunno, don't care. For what its worth, they came out with the new "Negative Gravity" model which reach full braking force sooner than the zeros and have beefier arms.

ExMachina

mmmm-K....still think they were installed wrong. i've got mine right here in front of me w/ the wheel off and i can't budge them off-center, even with a good knock from the tire...YES, they will move a tad out of alignment and then stay kind of cocked-ass because of the cable friction, but as soon as i reinstall the wheel and give a quick squeeze on the brake lever, they're back to perfect alignment. the portion of the calipers that clamp to the fork doesn't move an iota.

umd

The Jittery Joe's Team uses them...

I have the negative G's, not the Zero G's. I can say that they're a royal PITA to set up. It's all doable, but just takes a long time. However, once they are set up, they seem to be just as functional as the Ultegra's that they replaced.

Lt.Gustl

It wouldn't be too hard to make a test rig and find out for sure which work best. It's not like frame material/stiffness or geometry arguements that are impossible to win and mostly in your head. It's pretty simple really. Also even an old centerpull on (dry)chrome rims will lock up both wheels set up properly and with fresh pads. Unless the parts break or have poor modulation I don't see why there would be any trouble. Aside from all that brakes only slow you down, you're buying new ones to go faster? that doesn't make any sense.

EGreen

So split the minuscule difference and go with Ultegra!

patentcad

Twice.

+1 Gazillion.

Save some weight AND some cash and get a set of TRP R920s.

umd

How do you figure you would save weight with those? They are still 100g heavier than the zero g's.

Treefox

They don't have a very good weight to cost ratio. There are cheaper places to save weight which won't affect performance.

Then again, I'd have to point out to you all that if the point of cycling is to go fast, you're better off with poor brakes, as they'll slow you down less.

Tangentially-related...

What's the lightest dual-pivot brake out there?

jrennie

The trp 920's are 128g claimed and 130g real weight but I think the lightest dual pivot is the KCNC at 160g for the set. Retail is around $300
