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, zipp 404 firecrest carbon clincher wheelset, 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. If flat land speed is what you're after, these are clearly a good way to get it. So, if your ultimate goal is flat-out speed and you're not interested in tubulars, there's a lot to like with Zipp's new Carbon Clincher - they're fast with zipp 404 firecrest carbon clincher wheelset big, fat, capital 'F' and offer handling stability in crosswinds unmatched by other aero wheels we've used.

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. As you can see in the illustration below, they are very wide at the tyre

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 404 firecrest carbon clincher wheelset. Here's how you can win it. So, if your ultimate goal is flat-out speed and you're not interested in tubulars, there's a lot to like with Zipp's new Carbon Clincher - they're fast with a big, fat, capital 'F' and offer handling stability in crosswinds unmatched by other aero wheels we've used.

A fast road wheel is only as good as its ability to maintain speed and traction in a variety of conditions. Pros Consistent speed in wind Maintains structural integrity under heat Accelerates quickly Reliable and stiff handling Cons Can get significant heat buildup when braking, which can affect reliability of brakes The braking tends to be touchy and may squeal in wet conditions. However, like most road wheels, this one has a few stand-out features that set it apart from some of its competition, including: 58mm Rim Depth. Generally, the deeper the rim of your road wheel, the faster you can expect to go Source: CyclingWeekly. The Zipp Firecrests have a depth of 58mm, which is one of the widest depths for road wheels. In fact, Zipp created the Firecrest series as the first deep-profile wheels to have incredible aerodynamics and speed while not compromising their ability to be responsive and handle reliably. The Zipp 77 front and rear hubs are what the Firecrest Carbon Clincher v3 Road Wheel uses to improve its spin and performance. This hubset is one that Zipp also considers to be a more simplified option for cyclists, meaning that it requires little maintenance and upgrades. Zipp also uses its Wire-EDM technology on the hubset, allowing them to go through a heat-treating process before they are cut to their precise measurements using the technology.

At 58mm deep, the Firecrest Tubeless is ideal for road races, time trial and triathlon, gran fondos, and riding over varied terrain. With hookless, the transition between the tire and the rim is more seamless and aero.

Zipp says this infrared image shows the superior heat capacity and dissipation capabilities of its new Carbon Clincher rim. I simply wanted to share my positive experiences with these wheels with you. Weight - or more specifically, inertia - seems to be the culprit here. James Huang. If flat land speed is what you're after, these are clearly a good way to get it. But despite Zipp's claims, the rims still don't dissipate heat as well as we'd like, and certainly still not as well as an aluminum hoop. In all fairness, the rim weight is inline with similarly-sized carbon clincher competitors, especially considering the Firecrest shape's abundant surface area. Since I typically use carbon wheels during racing, I always went with the tubular version of whatever wheel I owned. 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!

Brass washers on the included skewers operate produce a silky smooth feel that nylon washers simply can't match. Zipp includes its own cork-based Tangente brake blocks with each set of Carbon Clinchers.

The is a classic in Zipp's arsenal that dates back to the early s. Originally designed as a TT and race day specialist, the has evolved to it's current Firecrest shape making it well suited for all-around race-day and training use on any terrain.

The rear hub features tall flanges to help transmit power to the rim. After using these wheels for one year I will need to update you on the quality and reliability of these. But despite Zipp's claims, the rims still don't dissipate heat as well as we'd like, and certainly still not as well as an aluminum hoop. James Huang. What I do know is that tyres slide onto the rim without any difficulty during installation and I have always been concerned about this. These are not just a revamped version of the tubulars. Heading out the door? UPDATE: Zipp have confirmed a number of enhancements to the hubs and the rim construction to rectify these problems which they acknowledge. In short, unfortunately I cannot recommend these wheels after experiencing the problems myself and my team have had. 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. It took a little bit of getting used to when looking down at the wider rim profile. This test is done in still air to ensure the minimal amount of convective cooling possible and we still manage to shed over degrees in a single revolution in still air.
