Strengths: Look niceWeaknesses: Expensive
Poor stopping power
Difficult to set upBottom Line: When I could get these to actually work,they were not nearly as good as campy record,poor stopping power,especially back break. Sent them back to ciamillo to get refurbished.After this I could never get them to work right,couldn't stay centered,etc.Very difficult to set up even following all directions,torque wrench,etc. Sent them back and switched back to campy.Of note,they kept my brakes ,never sent them back even after several emails.Not an honest company!!

Strengths: Weight, Looks. Great stopping power.Weaknesses: Changing the Pads. If you go with this brake stick with a carbon race wheel and a carbon training wheel. It will save your patience.Bottom Line: Brakes Perform Great. They are light weight and have a unique look. I use them with the yellow swiss stop brake pads on carbon AND aluminum rims. The pads work well for carbon and are OK for aluminum. The biggest reason I don't change out the pads when I change rims is that it is an absolute pain to change the pads. I was used to shimano brakes that are super easy to change pads. These are tough. That's why I just use the Yellow Swiss Stops. They work with both rim materials and do not pick up any aluminum residue in the pads that will ruin your carbon rims. However, I always wipe the pads clean when I change to carbon and sometimes rub them with light sand paper just to make sure there is no grit stuck in there to ruin my carbon rims.
As others have mentioned, the brakes are a little more finicky to set up. It can be difficult to get them centered and to keep them centered. This sometimes requires a tool to get it just right after switching wheel sets. Usually this has not been a problem but it could be during a race if you have a tire blow out and switch rims. You might end up with wheel rub if you are not careful.
The only other problem I have encountered is the opening width of the brake. When you open them up to change wheels, sometimes it just isn't enough. Especially if you have new pads and a narrow profile rim versus a wider carbon profile rim. Not too big of a deal most of the time as long as you have some slack in the adjustment nut.
Bottom line: if weight is an issue, this is the brake. 1 Dura Ace brake weighs almost as much as 2 Zero Gravities. If you have an arsenal of wheel sets with various rim materials, stick with a brake that is easier to change pads.

Strengths: Great product, light weight. Most importantly, they work!!Weaknesses: Others not setting them up correctly, and giving bad reviews.Bottom Line: These brakes STOP. Take special care in setting these brakes up as they are different than most. If done properly, they have a great solid feel and modulation.
I've never used a set of road calipers that stop this well. These things would stop a train.

Strengths: - Super light weight
- Great modulation
- Stop on a dime
- Sharp looking brakes
Weaknesses: Getting them dialed in takes a little patience. Adjusting the cable tension takes patience as they don't have that orbital pad adjustment screw that Shimano and Campy have.Bottom Line: I've been using Campagnolo Chorus brakes on my current bike and in addition to not liking the stopping power, they weigh a ton! Did a lot of reading on these zero gravity brakes which are super light and they seemed great, and I got a killer deal on top of that. I had read mixed reviews from people who praised these brakes and also a fair share of people who adamantly hated these brakes. I got a good enough deal that I decided to take a chance and try them out.
First off, these brakes are nicely machined with lots of attention to detail. Very simple design and simple operation. Contrary what other may have said, installation was no harder than Campy/Shimano brakes. Just follow the directions in the video on the zero gravity website and it's a breeze. However, tweaking them to get the right feel does take a little more patience, but I wouldn't say that they are hard to install.
Mine came with yellow Swiss Stop brake pads made for carbon rims which I immediately swapped out for a set of black Kool Stops made for alloy rims and all I can say is WOW. I briefly tried the yellow pads on Ksyriums and it felt like junk- very poor stopping power. One the Kool Stops were on these brakes rocked! There is excellent feel to the brakes and has a very progressive feel to it, similar to a motorcycle. Not sure what brake pads other reviewers who had mixed reviews were running but black Kool Stops for alloy rims matched with these 0G brakes are awesome.
Overall, it's a nice upgrade over my Campy Chorus brakes (non-skeleton) and literally dropped about a 1/4 pound off the bike weight. Great stopping power which is just as good, if not better than my Campy brakes and have very nice modulation. They're expensive, but when a product lives up to all the hype, it's worth it.

Strengths: Strenght to weight, design, modulation and originality. Ample braking power for my weigth(160) even with worn pads.Weaknesses: Price, not as easy to adjust as shimano. Front pads too close to the fork leg (I used a spacer).Bottom Line: Two test rides, a long and very vertical one and I can say these are keepers. I dont understand the gaps in the different reviews: people love or hate these. May be its the finicky ajustment or that they use the wrong pads. I use the green Swisstop that came with the brakes and have no problem stopping/slowing down even going downhill at 70kmh (43 mph).
Bottom line: these are not shimano brakes and dont feel the same, they actually feel better in modulation(for me) since the response is more gradual as you apply pressure, my ultegras are more linear.
The modulation is good, the feel is different from the very ordinary ultegra stoppers i was using. I did not expect such power and it was a pleasant surprise to have that good of a feel from the relative minimalist design. It's like older 80's brakes but well designed, they are like a single pivot but the cam system really works like a double pivot.
They need a bit of patience when you do the initial setup (not as much range as typical campy/shimano) but once you get past that there sweet. I will concede that a larger rider might not get the needed confidence these provide and suggest that they look to the beefier redesigned Negative G's that have a better leverage ratio.
For adjusting just use two hex wrenches in both ends of the main bolt and rotate in the same direction, no need for a 13mm wrench.
