a new chapter in speed a better wheel in every way

Aerodynamics calculation methodology: Time and watt savings over 40km
are calculated using a top-selling aluminum race wheel as the baseline and
assuming a power output of 300 watts and a speed of 30mph (48kph). If
you’re going slower, the time savings are greater, as you’ll be riding for a
longer time. | Aero savings reflect rider-on-bike testing, not wheels-only
testing. All numbers are calculated at a 10° wind angle to approximate
the most common real-world riding conditions. Tests are conducted using
21mm Vittoria tires; Zipp Tangente tires can save an additional 3-9 seconds,
or 1-3 watts.

Zipp® Carbon Clinchers have been described as the most heavily anticipated
wheels of all time. During the two-year development process, we designed
new clincher-specific approaches to prototyping, testing, materials, and
manufacturing. The end result is worth the wait.
For every rider, every discipline, and every ability level, aero wheels make a noticeable difference.
Now, Zipp wheels make a bigger difference in more ways than ever with the revolutionary Firecrest
rim shape. Used in our 404 and 808 Tubulars and Carbon Clinchers, FirecrestTM is not only more
aerodynamic than any other design, it also improves handling, wheel strength, and overall ride quality.
Optimized aerodynamics | Wind tunnel development has allowed us to perfectly
match the real airflow patterns created by fully inflated clincher tires to the rim.
This not only improves the speed and handling of our wheels but also means you
don’t have to sacrifice aerodynamics when choosing clinchers.
More speed | Discovered as we developed our Carbon Clinchers, Firecrest refocused our thinking from
the front to the back of the wheel. Whereas past designs tapered inward from the widest point of the
toroidal bulge, Firecrest maintains its width nearly all the way to the spoke bed. Firecrest is the first rim
shape designed specifically to control airflow around the back half of the wheel.
Optimized materials | Chemical engineers from our US-based composites
supplier traveled to Zipp to develop an exclusive heat-resistant resin. This
technology improves heat dissipation so substantially that ours are the only
carbon clinchers to pass stringent limitations on rider weight or brake
pad options.
More stability | Using computational fluid dynamics
(CFD), Zipp engineers adjusted the Firecrest profile
so that the center of pressure moved closer to the
steering axis. As a result, Firecrest rims provide
markedly more stable handling than other rims of
equal or even shallower depth.
Optimized ride quality | Our proprietary heat-resistant materials, Tangente High
Performance Cork Brake Pads, and angled braking surfaces provide smooth,
pulsation-free stopping power under all conditions.
Inflating with water instead of air saves rims and eardrums when
testing for maximum tire pressure.
More strength | As we demonstrated with the
Paris-Roubaix-winning 303, a wider rim increases
lateral stiffness for sprinting and cornering yet
offers greater vertical compliance for more control,
comfort, and durability on rough surfaces.

FASTER THAN THE SUM OF
THEIR PARTS
The fastest riders make the most of their strength by studying the
course and scripting every effort ahead of time. The fastest wheels
turn technology into performance by designing every component
to work in unison. | At Zipp®, we believe that systems work best
when individual parts are developed in the context of the whole. This
philosophy leads to features like rims designed to protect your tires
and hubs with spoke holes drilled at varying angles depending on rim
depth. Combining all those details results in wheels that are perfectly
matched to the bikes you ride, the courses you confront, and the
goals you’ll achieve.

The 101 is a legitimate high-performance wheelset.
Its wind-tunnel-developed, 30mm-deep rim shape
is faster than many deeper V-shaped rims and
can save up to 42 seconds over 40km compared
to the industry’s benchmark aluminum wheelset.
