404 650c Firecrest Carbon Clincher - Zipp’s 404 650c Firecrest Carbon Clincher wheelset offers smaller athletes superior aerodynamics, stability, durability – and proper fit. It’s a simple premise, really. But for smaller athletes it has been a challenge to find the most advanced, highest performance wheelsets. With limited options in the 650c size, many of these cyclists ride standard 700c wheels and lose out on the increased efficiencies of a correct fitting wheel.
Smaller athletes will never have to make this sacrifice again. The 404 650c Firecrest Carbon Clincher allows smaller bikes to fit smaller athletes. After all, road bikes were made in two wheel sizes – 700c and 650c – to keep handling and positioning proportional. High-end bike shops are making fit a top priority, helping riders to reach their maximum potential.
Its Firecrest aero profile is the first deep-profile carbon clincher design to offer the superior aerodynamics, ride quality, strength and handling of a wider rim body. Yet the 404 Firecrest Carbon Clincher weighs just 1,495 grams per set, putting it among the lightest deep-profile carbon clinchers available.
The 404 650c Firecrest Carbon Clincher is at the forefront of the fit revolution while also building on the Zipp 404’s already legendary status. Its 58mm rim depth is a classic all-around performer that has carried athletes to scores of victories in triathlons, time trials, criteriums and road races. It also features two of Zipp’s most significant innovations – our proprietary Firecrest® rim shape and Carbon Clincher technology.
Firecrest - With the new Firecrest rim shape in our 404 and 808 Tubulars and Carbon Clinchers, Zipp wheels make a bigger difference in more ways than ever. Not only is Firecrest more aerodynamic than any other rim design, it improves handling in crosswinds, wheel strength, and overall ride quality.
ABLC - Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on most of our rims. ABLC smoothes airflow across the rim's surface and is tailored to every model from the 202 to the Sub9 disc. 2009 sees the third-generation of ABLC, with up to 4 times more dimples than before.
VCLC - Visco-Elastic Constrained Layer Control (VCLC) uses a vibration-absorbing material sandwiched between layers of rigid carbon laminate in the rim. When the wheel receives an impact from the road, much of the shock is absorbed by the VCLC system, delivering a 10% reduction in vibration.
88/188 Hub Technology - Every aspect of our 88 and 188 hubs sets a new benchmark. The standard steel bearings are the roundest in the industry. The 17mm axle is the stiffest of any road hub we've tested. The wire EDM-cut hub internals are the most precise. The SHIFT spoke hole technology is the most durable. When it comes to precision and performance, there's really no comparison.
Note: Zipp wheels for model year 2013 are compatible with cassettes of up to 11-speed to work with all modern drivetrains.
