Makiki-Tantalus Loop Bike Setup:
Merlin frame, DA drivetrain Summary:
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:
Great modulation and great mechanical leverage. Weaknesses:
Poor brake pad bolt design, high price. Similar Products Used:
Dura Ace, Ultegra

at DIrect EP Summary:
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. Strengths:
Only paid EP cost Weaknesses:
Read the review these brakes are over priced CNC junk. Similar Products Used:
Just about everything

at Helen's Cycles Favorite Ride:
hills above Malibu Bike Setup:
SEVEN Elium SG with Dura-Ace group and Mavic R-Sys wheels. Summary:
I originally ordered my bike with Negative Gravity Ti brakes. They were back-ordered so the shop gave me a loaner pair of Zero Gravity Ti brakes. These were terrible. Very weak braking, required a lot of effort on the levers. My hands would be sore all day after a big descent. I complained and the shop put on a pair of Dura-Ace brakes. What a difference! I finally had real brake power on steep descents. Then my Negative Gravity brakes came in. They were somewhere in between the Dura-Ace and Zero Gravity brakes. I tried to live with them for a few months. Tried different pads without much improvement.
Finally I got sick of too little brake power and sore hands, went back to the Dura-Ace brakes. Much better! I won't be going back to Negative Gravity brakes anytime soon. Strengths:
Lightness, decent modulation. Weaknesses:
Weak stopping power. Kind of ugly. Similar Products Used:
Dura-Ace, Negative Gravity.
