There are certain fundamental bike-related decisions we've all faced: Shimano or Campy; Fizik or Selle Italia; Continental or Vittoria? No decision, though, seems to cause the consternation of the power-training neophyte: Power Tap or SRM? There are a dozen arguments for choosing either brand.... read more

Even though this wheel comes with a full-blown Power Tap 2.4 wireless powermeter in the hub, it still offers all the aerodynamics of the standard 900 disc. It has only 19mm of frontal area, so it's nearly invisible to the wind. It has a dimpling pattern unique to the 900, which helps smooth the... read more

An interesting observation for you: Zipp's 900/Power Tap 2.4 disc wheel is approximately 50g lighter than the Sub-9/Power Tap disc. According to Zipp's testing, it's also laterally stiffer than the Sub-9. And, amazingly enough, it's 10% less costly than the Sub-9 version. While the Sub-9 offers... read more

The pain of progress is felt by the early adopters. Yes, the first generation of whatever new design is paradigm-changing, but the second, third, and fourth always get better and better. And the new Zipp 202 wheelset will really hurt those who own a previous iteration of these superlight climbing... read more

To choose is to live. We have to admit that we find ourselves splitting hairs when choosing between the Zipp 303 and the 404 as the ideal racing wheelset. They're both feathery light and extremely aero, with the 303 being a bit lighter and the 404 being a bit more aero. What should be the tipping... read more

We used to think of the Zipp 404 as a wheel for the big rouleur riders. CSC's Jens Voigt is a perfect example. Then we saw Oscar Pereiro riding these rims in the mountains of the '05 Tour. The aggressive Spaniard, who appears to be on the small side of mean and median height and weight, spent... read more

There was a time when a 35mm deep rim looked oddly deep. In that era, 19mm deep box-section rims were the norm. Nowadays, 35mm looks normal. And at 82mm deep, wheels like the Zipp 808 look deep. The tubular version of the 808's rim is only 460g, which is lighter than many box-section clinchers.... read more

We'd love to be a fly on the wall at a Zipp imagineering session. Like for this Zipp 1080 Tubular wheelset. Zipp started with a few knowns, like the fact that some people already can handle Tri-Spokes in crosswinds. They then used that info to figure out how they could make a wheel that's faster... read more

A good thing to know about Zipp's FlashPoint 40 is that they come with no pro endorsements. This is not a pro wheel. We see that as a good thing. Just like using Chorus or Ultegra, this wheel has most of the performance of a pro wheel, at a price that's more back down to earth.

The FP... read more

One of the hardest things to explain to ourselves is how a heavier rim can be faster, even uphill. There are online calculators that can give a numeric value to the differences and prove the heavier can be faster -- if it's more aero. It's as if the weight doesn't count any more. Then again, we... read more
