Zipp 404 firecrest carbon clincher wheelset

Zipp's new 58mm-deep Firecrest rim profile admittedly takes a while to get used to, what with its unusually fat width, nearly board-flat sides, and decidedly blunt nose but when out on the open road the only thing you're likely to think about is, 'holy crap, I'm flying! During one memorable instance on a familiar, fast and slightly negative grade, we actually had to sit bolt upright and feather the brakes to avoid overtaking a similarly-sized rider that was well up the road and clearly pedaling like mad, zipp 404 firecrest carbon clincher wheelset. If flat land speed is what you're after, these are clearly a good way to get it.

Here's how you can win it. Zipp released the new Firecrest wheels in the middle of last year. The biggest difference over their previous models is rim shape. These are not just a revamped version of the tubulars. Zipp widened the sidewalls on the Firecrest.

Since I typically use carbon wheels during racing, I always went with the tubular version of whatever wheel I owned. As you can see in the illustration below, they are very wide at the tyre However, when the Lightweights took a tumble , they were expensive to fix or were relegated to the garbage. But you won't see these wheels under a ProTour rider anytime soon; drawbacks such as the stiff ride, so-so weight and high inertia for a pure race wheel , screaming brakes, and high price tag for the rest of us are tough to ignore. You triathletes reading should be salivating over these wheels. Say what you will about the debated effects of wheel weight on overall acceleration - we know it's a small percentage of the total bike-plus-rider mass - but it's still a noticeable difference nonetheless. According to Zipp, the Carbon Clincher's new composite system was specifically designed to withstand high heat - the most common mode of failure for full carbon clincher rim beads. Cones in the hubs constantly coming loose 3. Hub bearing preload is easily adjusted with these threaded collars. Spokes constantly loosening 2. Zipp widened the sidewalls on the Firecrest. In addition to being admirably stable in those conditions, overall handling is predictably rock-solid and confidently surefooted in hard corners thanks to impressive lateral rigidity - feel free to go just that little bit faster or lean it over just that little bit further and these wheels will likely pull you through safely. Zipp is also keen to point out the higher heat capacity of its new composite system - a critical feature as tire bead softening is a known Achilles' heel for carbon clinchers, especially for riders that live in mountainous regions. Heading out the door? Indeed, in our test the s have proven to admirably maintain their structural integrity under high heat conditions with no disconcerting thumping under continuous braking - a telltale indicator that the bead hooks are giving way.

Sapim CX-Ray stainless steel spokes. The total weight of the Firecrests is 1,g g front, g rear. Plus, clincher rims that are significantly lighter or offer a smoother ride - whether they be carbon or aluminum - are apt to be substantially shallower and include fewer aero benefits. Zipp's new 58mm-deep Firecrest rim profile admittedly takes a while to get used to, what with its unusually fat width, nearly board-flat sides, and decidedly blunt nose but when out on the open road the only thing you're likely to think about is, 'holy crap, I'm flying! I simply wanted to share my positive experiences with these wheels with you. Many manufacturers place the spoke nipple inside the rim for aerodynamic reasons. When these get rolling in a straight line they are noticeably fast. The biggest difference over their previous models is rim shape. Actual rim weight is just over g and while that's not necessarily heavy per se, all that mass is concentrated at the outer edge of the wheels where they have the most effect. Say what you will about the debated effects of wheel weight on overall acceleration - we know it's a small percentage of the total bike-plus-rider mass - but it's still a noticeable difference nonetheless.
