Tubeless, no hooks Zipp wheels for a uniform rim-to-tyre interface, the new 858 NSW and 808 Firecrest models take triathlon and time trial speed freaks to the next level. Increased rim width for wider tyres and lower tyre pressure to slash rolling resistance and reduce body fatigue caused by road buzz. More than 240 grams lost in weight without compromise to rim's strength.
For this year, Zipp engineers attacked the four primary barriers to speed – Air, Rolling Resistance, Gravity, and Vibration – head on with the in-house developed Total System Efficiency technology, a novel approach to aero wheel design.
On the air resistance front, Zipp-patented Sawtooth rim profile on the 858 NSW continues to push aero efficiency and crosswind stability to new highs. The now legendary Firecrest rim shape, dressed in a complex dimpling pattern to save watts when slicing through the air, will nudge you ahead of your rivals in an aero game the moment you hook up the 858s or 808s to your bike.
Zipp widened 858 NSW and 808 Firecrest rims to 23mm on the inside to give wide tyres more platform to sit on (28mm tyres worked best in testing). With that, rolling resistance dropped and, simultaneously, lower pressure minimised energy loss to vibration and reduced body fatigue.
To help fight gravity dragging you down when the road shoots up, the new 858 NSW shed 243 grams off its weight and the 808 Firecrest 274 grams. Yes, you read that right – 243 and 274 grams without losing any rim strength.
Chris Langdon, Echelon Sports Director Says:
“The new 858 and 808 represent Zipp’s drive to make you faster. It’s not just aerodynamics anymore, it’s the whole package – less rolling resistance and vibration, less fatigue and less weight. It’s a major step forward in aero wheel design.”
