    Strengths:    unheard of customer service! These guys go outta their way to please...

    Weaknesses:    still looking for one...

    Bottom Line:   
    These are lighter then my Dura Ace brakes and stop better too. They are great, but if you do have a problem with them shoot an email to them and Ted Ciamillo will personally take care of you!

    Strengths:    Strong, light, beautiful. PLENTY of power.

    Weaknesses:    Swissstop pads...ugh. A little hard to clean b/c of the nooks and crannies.

    Bottom Line:   
    Very nice brakes. Stopping power is not a problem...with Kool-Stop salmon pads. Yellow Kings are crap-IMO. Yes, they do tend to go off-center at times, but nothing major. A friend of mine uses them and he weighs 220lbs...He uses the black Kool-Stops with no problems. I'm around 157lbs, though.

    Strengths:    Light
    Sexy
    Performance


    Weaknesses:    Cost- maybe, but they can be picked up for around the same price as DA, and they weigh less


    Bottom Line:   
    I replaced a set of DA 7800s with these. I was expecting to lose some performance and have a bit of a harder time braking, especially with the carbon wheels. I feel like I have every bit of stopping power and have no noticeable difference in terms of power. I have had several instances where I had to almost lock the brakes in a pack and I was able to stop right along with everyone else.

    I am also a bit of a clydesdale, so this concerned me as well, but it turned out to be unfounded. I think the reality is that the weight savings are nice, but not overly significant and the performance is on par with DA. I personally bought them more for the all black look than anything else, but I wouldnt have kept them if they didn't perform.

    Strengths:    Great modulation and great mechanical leverage.

    Weaknesses:    Poor brake pad bolt design, high price.

    Bottom Line:   
    Switched over to the Negative Gs (NGs) from Dura Ace 7800. I am running Reynolds KOM rims. The NGs come with SwissStop Yellows and previously I was running the Dura Ace with Zipp carbon pads. The NGs with yellows provide better brake modulation compared to the the previous DA setup. I feel I am able to modulate braking power on the NGs to a finer degree. There seems to be less slack in the cable train in the NG setup. However, I'm not sure if this is due to the calipers or the pads. And yes, the NGs do seem to provide more mechanical leverage than the DA setup.

    The NGs do have one major design issue. The supplied brake pad bolt has a 3mm allen key head. The installation instruction calls for 70-80 inch/pounds of tightening torque. It is impossible to apply that much torque with such a small allen key without slipping. I eventually switched over to a standard hex head bolt.

    Strengths:    Only paid EP cost

    Weaknesses:    Read the review these brakes are over priced CNC junk.

    Bottom Line:   
    Bought the most "powerful" version of zero G brakes as I was looking for an idustrial looking brake for the fixed gear and thought they would also perform. I ordered these brakes with pads for allow rims, they came with the yellow carbon pads. Strike 1. Called asking for them to ship the correct pads in which I had originally ordered. Needless to say Customer service is seriously lacking. Strike 2. Now when it comes to performance these things are very weak. I can stop faster just by applying back pressure. Strike 3. The yellow pads are nothing short of being worthless on an alloy rim and lasted only 40 miles of me attempting not to use the brake. Even thought I only paid EP pricing I still feel as if I was ripped off. Bottom line save your money and buy some thing else.
