Manufacturing a new wheelset, from the design team’s conception to its final touches, is a significant challenge for a brand. Improving on the current version, which already performs at the highest level, makes it even more challenging. This is precisely the case with the new 353 NSW, which Zipp has just released.
Based on one of the brand’s flagship models, after much effort, they have achieved a significant advancement within their wheelset portfolio. The new 353 NSW are still considered road-only racing wheels with a climbing profile, but with substantial performance improvements compared to their previous model. The wheels are now lighter (1,310 g), more durable, and feature improved aerodynamics. Despite all the above, the main innovation of this model is its connectivity with the entire AXS universe through a revolutionary air pressure sensor integrated and hidden in the carbon rim itself.
A step forward
A few devices from external companies can accurately measure tire pressure in real time. Now, Zipp offers the possibility of incorporating this recent technology natively into its revamped 353 NSW model.
What may sound like a useless feature for an amateur cyclist can actually make a difference from a more racing perspective. Knowing at all times if a tire is losing air, if you’ve chosen the correct pressure for the type of terrain you’re riding on, or if the pressure before starting your ride is the correct one are just some of the scenarios in which we believe this sensor can be helpful.
The AXS system’s compatibility allows us to easily view tire pressure from a bike computer or mobile phone. We can also check the battery status of the sensors, perform firmware updates, and configure them. In addition to connectivity, the wheels feature an LED that will turn green if the tire pressure is correct and red otherwise, so we can visually tell if we are ready to go.
We would like to note that we are always talking about a pressure sensor that allows you to monitor the air in your tires, however it is not a real-time air control system that inflates/deflates them.
Specs overview
We could talk for hours about the specs of the new 353 NSW, but we’ll try to summarize and tell you what we believe is essential to highlight.
This new version features a carbon layup and composition, making this Zipp model the lightest and stiffest (16% more resistant than its predecessor) in its current carbon disc brake wheelset portfolio. Furthermore, the technology to achieve the unique wave-shaped rim allows for great aerodynamic results. The Zipp 353 NSW comes with the high-end ZR1 SL hub, which features ceramic bearings and has also been improved, resulting in a decrease in weight by 30 grams compared to the previous version.
Last but not least, we’re talking about hookless wheels compatible with tubeless tires, with the option of installing an inner tube with a threaded valve stem. The internal rim width is 25 mm, which is optimized for 30 mm tires. During its presentation, the brand emphasized that this model is not approved for gravel use.
