ZIPP 404 Firecrest™ Carbon Disc SHIMANO HG 28"/700C Rear Wheel for Disc Brakes, MY2022

ZIPP 404 Firecrest™ - the rear wheel for any purpose, paired with modern disc brakes!
The 404 series is a real all-rounder and a true classic, a standout in the portfolio of US premium manufacturer Zipp. This series started the ZIPP Firecrest™ Revolution in 2010, with their rim profile designed according to the wishes and needs of competitive riders and triathletes. It stands for extreme stiffness, aerodynamics, reliability, and stability.

For the 2022 model year, ZIPP has given its almost legendary Speed Weapon a hookless rim for tubeless tyres, which enables an almost seamless transition between rim flanks and tyre, further minimising wind resistance. At the same time, the rim has become lighter, so that the weight of the wheel is even lower compared to its predecessor. It is tubeless-ready and has a inner rim width of 23 mm, so the ZIPP 404 Firecrest™ can handle the modern trend towards wider road bike tyres, while also providing low rolling resistance, increased comfort, and improved grip when riding tubeless.

This high-end carbon rim was handmade in Indianapolis (USA) and has a symmetrical, 58 mm high rim profile. It can achieve its aerodynamic potential in a variety of disciplines – whether triathlon, time trial, sprints or classic stage racing, including mountain stages. Thanks to the ABLC™ dimples, the wheel Firecrest™ rim profile has excellent aerodynamic properties, as well as very high side wind stability (AeroBalance™). You’ll be even faster, despite putting in the same amount of power, and can shave off a few seconds when it counts.

The middle of the wheel features the German-built ZIPP ZR1 rear hub with an improved seal and a freewheel with 66 points of engagement and 6 pawls. This equips the ZIPP 404 Firecrest™ with responsive acceleration.

Highlights:
• Firecrest™ technology: The rim profile has rounded edges with a consistent width - this counteracts crosswinds and lets you control your wheel better.
• ABLC SawTooth™ technology (Aerodynamic Boundary Layer Control): The many small nodes on the rim’s outer surface optimise the aerodynamic balance and improve crosswinds stability.
