Detailed Description

After Zipp debuted their Firecrest technology in 2010 with the then-new 404 Carbon Clincher, they were stuck with a problem. How to make the fastest wheel faster. The answer to that question is found here with the Zipp Firestrike 404 Carbon Clincher. It's a wheelset that goes well beyond the benchmarks Zipp set with the Firecrest.                         The idea was to make a wheel that was only faster, but stronger, better stopping, lighter, and ultimately, more confidence-inspiring. They, not surprisingly, hit all the marks. But they needed to make several changes in order to get there, changes that could impact the way your ride. Aerodynamics. They wanted to make the wheel better in a pure headwind, or zero-yaw conditions. But it was more important to improve performance in crosswinds, or conditions where the wind is coming from anywhere between 2.5-degrees to 20-degrees to either side. With winds that come from the side, they're never at a 90-degree angle, as moving forward changes the effective direction of the wind. The wheel is faster in no wind or headwind conditions. In crosswinds, you'll get a 34% reduction in side forces, meaning not only is there less wind resistance in these conditions compared to the fairly sidewind-invisible 404 Firecrest, but it's easier hold the bike in a straight line, spending more of your focus and energy propelling the bike forward. They accomplished this in two ways. First, changing the shape of the rim. The 404 Firestrike has a 26.4mm exterior width at the brake track, similar to the 303 Firecrest. It gets wider as it moves toward the spoke bed, to 27.8mm at the widest, wider than the 404 Firecrest by 1.27mm, and shares the 404's 58mm depth. Second, they further tuned the ABLC dimple pattern. The pattern is visibly different than earlier iterations, a new design created to minimize the dreaded vector-shedding phenomenon, where the wind pressure builds on one point of the wheel and then dumps, reducing pressure dramatically. Ever see a flag ripple in a strong wind?  The rippling is from vector shedding; it not only can increase resistance, but also make steering harder. By changing the shedding, by first minimizing the possibility then tuning the for higher frequency and shorter duration, there's less force pushing the wheels around. Stronger. Zipp found a new resin to go along with their carbon-fiber. Add a newly-designed molding process and the rims more impact-resistant than ever. Better braking. First, Zipp found a new texture, Silicon Carbide to add to the brake track. It improves braking in all conditions. Since that wasn't enough, they molded channels into the brake track to better disperse water. They're small enough and close enough together that there is no pulsing or gripping in the dry. In the wet, they're designed to channel water away from the braking surface. As a result, wet-weather braking will not feel as if you're waiting for the pads to squeegee water. Zipp calls this Showstopper technology and their testing has found it results in better braking than the average aluminum rim, and equal braking to industry-leading aluminum rims. Lighter. While they were able to better manipulate carbon and resin to save weight at the rim, the bigger advances happen in a few other places. The Zipp decals of old have been replaced with screen-printed graphics. The graphics are not only lighter than stickers, but also don't interrupt the dimple pattern, which is a benefit to aerodynamics as well. The rear hub, the 188v10 has been relieved of all unnecessary material. It might look like it possesses taller flanges, but that's just the excess material removed to create a lighter, equally strong skeletonized shape. The hubs, btw, have been improved as well. They've had the pre-load wings of the earlier iteration removed (no pre-load, nor adjustability needed), and higher-quality ABEC 3, Grade 10 ceramic bearings have been installed. The hubset overall has gotten a 20g diet from the v9 iteration, and it possesses 5% greater lateral stiffness, and 25% greater torsional stiffness than the popular DT240 hubset. The wheelset is packaged with several Zipp goodies: titanium quick releases, rim tape, Tangente tubes and valve extensions, Tangente Pro Evo brake pads, and wheel bags. Pads/cassette can be had in either Campagnolo 9/10/11 or Shimano/SRAM 9/10/11. At this point, only Zipp Tangente Evo pads have been approved for use with these rims. The Zipp Firestrike 404 Carbon Clincher is Zipp redefining fast. Again.
