Carbon wheels are aero, stiff, and featherweight, but if they chatter like hungry pigeons when you try to slow down, that's going to diminish your riding experience. The Zipp Tangente Platinum Pro Brake Pads transmit smooth, reliable stopping power to carbon braking surfaces through all weather conditions. They've been put to the test in the Tour de France; we've ridden them, too, and can attest to their performance.Nearly any brake pad can bring you to a complete halt, but it's the lighter touches required in the peloton and through S-turns that separate the best pads from the pack. Zipp worked with SwissStop to develop the Platinum Pro pads, with the goal of blending smoothness, long wear life, and wet-weather performance. When set up correctly, these pads won't grab, they won't damage or discolor your expensive carbon rims, and they'll help you scrub speed safely, even in a downpour. Some important things to point out: The Zipp Tangente Platinum Pro Brake Pads are designed to provide superior braking performance for carbon rims, so they're not approved for use on aluminum braking surfaces. Zipp also describes them as being roughly 1.2 mm wider, relative to the brake caliper, than Zipp's High Performance Cork Pads. Some additional adjustment of the brake caliper may be necessary, especially when riding the latest wide rims. The Platinum Pro Brake Pads ship two to a package (enough for one brake caliper), and in two versions-a Shimano/SRAM-specific style, and a Campagnolo-specific style. Please note: The Zipp Tangente Platium Pro Brake Pads are compatible with Shimano, SRAM or Campagnolo 2011 brake pad holders
Strengths: This review is not really addressing how good these pads are, but rather to note one wheelset for which they are not recommended. See Weakness.
Weaknesses: I have a set of 2012 Easton EC90 Aero wheels. I had them on a bike with the yellow SwissStops and braking was great. When I received my new 2013 Trek 6.9, the LBS suggested installing the Zipp pads. I was aware of the reviews and agreed. Immediately, the braking power was different, but hung in there wondering if it was just poorer braking with the new integrated Bontrager brakes. I finally decided it could not be and "trekked" to my LBS with the old pads and had them check out the brakes and to switch out the pads after an SUV almost ran me over and I was not as able to avoid the cell phone using driver as easily as I should have due to very poor braking. They checked the Zipp pad braking ability with the brakes in full compression. The wheel still spun reasonably easily. The Zipp pad and the braking surface on the Easton's were not meant for each other to the point of being unsafe. The only change made was to first put in the SwissStops. The brakes were not adjusted. The stopping power was immediate and extremely better with them. As I am only 175#, not a racer and don't live in an area considered hilly, heated up rims are not an issue for me. Stopping is important. So, while the Zipps may be great in many applications, it is awful for use with the Eastons.
Zipp pads may be fine, just don't use them with the Easton EC90 Aero's. In fact, doing so is particularly unsafe.
