The Zipp 404 S offers the ideal balance of weight, aerodynamics, and aesthetics to the discerning cyclist.
Fit for road racers, criterium specialists, or any high-performance pavement rider. At 50mm deep, the 404 S rim’s mid-depth profile provides premium level aerodynamic performance while staying shallow enough to maintain stability in crosswinds. Paired with a 23mm internal rim width, this TSS wheel allows for 28-40 mm width tires to be run at lower pressures for optimal rolling resistance and control on nearly any road condition.

I used to have an Edge 540 Solar which was not touch, and it was truly a pain to use. It felt like it was designed to be touch, then last minute added as a non-touch option. But I did like the data screen and the size. The solar charging was minimal, so when my Edge 540 was stolen I opted for the touch version without solar and I couldn't be happier! It has a good battery life, touch works so much better than the button versions, and the lack of a solar frame helps in certain light conditions as the solar frame would provide some glare once in a while. Highly recommend!
Sierra Bicycle Supply responded to my complaint in less than 2 hours and issued a refund for the defective tube.
This indicates to me that they are a good customer-oriented organization.
ORIGINAL COMPLAINT:
Both tires and tubes were well packaged and arrived safely. (All Condition Armadillo 700X25 and Standard Presta Valve tube 700X20-28C) I installed them and pumped them up with no problem. The next time I went to ride, the rear tube valve had a substantial leak. Loosening the nut and pressing the release pin resulted in a loud air leak that does not stop when I release the pin. The loud leak appears to stop when the nut is firmly tightened. I don't trust this arrangement.
I’ve had several cruxes, including an S works crux and for the money this is quite the value. I did a gravel race and cyclocross Race on my new DSW crux after cracking my S works frame in a Bike Crash. I was really impressed. Sure it’s about a pound heavier, but it has 90% of the performance. Great price point and probably more robust for CX.
