ALMSTHRE was created by three cyclists from San Diego, CA, whose relentless pursuit of endless adventures has always been in their blood. They seek to go further, explore more and connect deeply with nature, themselves and others. To feel alive, they believe that one should never stop exploring the unknown. They strive to get out of the comfort zone and always move forward. The art of doing is what motivates and inspires them, while passion is what fuels them. Therefore, when there is no end in sight, they keep pushing forward, because they are ALMSTHRE.
The New Frontier of Affordable Aerodynamics
The new Zipp 404 S wheels represent the evolution of the S-Series line, designed for cyclists seeking high performance without entering the most exclusive premium segment. Designed from the ground up to deliver maximum aerodynamic efficiency on the road, they combine technologies derived from wheels used at the highest levels of professional cycling with excellent value for the money.
Performance Designed for Speed
The 404 S was developed with a clear goal in mind: to be one of the fastest and highest-performing road wheels in its class.
Thanks to the new 50-mm carbon rim, the design incorporates many of the aerodynamic features of the renowned Firecrest wheels used in WorldTour races. The result is a wheel capable of delivering high speeds while also providing remarkable stability, even in crosswinds.
Uncompromising Aerodynamics
Compared to the already popular 303 S models, the new 404 S models offer further improvements in aerodynamic efficiency, saving up to 2 watts and delivering superior performance even compared to higher-end competing models.
The 50-mm average profile strikes the ideal balance between speed, control, and versatility, making these wheels perfect for long-distance rides, intense training, and road races.
Comfort and control on every ride
The 23-mm internal channel width accommodates tires ranging from 28 to 39 mm, allowing for lower tire pressures that improve rolling efficiency, comfort, and vehicle control on any road surface.
Tubeless Straight Side (TSS) technology was developed to provide greater safety and optimized performance for everyday use and long-distance riding.
Advanced hubs and low weight
The Zipp 404 S features the proven Zipp 76/176 hub set with 36 engagement points, a design that ensures reliability, smooth operation, and instant power transfer.
The wheelset is laced with Sapim CX-Sprint spokes in a two-cross pattern, helping to keep the total weight of the pair at just 1,585 grams.
