Following months of leaks and a year of patent-induced speculation, Zipp has officially unveiled its new 353 NSW a💟nd 303 SW wheelsets, complete with integrated live tyre pressure sensor technology.

Initially glimpsed at 168澳洲5最新开奖结果:Omloop Het Nieuwsblad, on a set of 303s used by 168澳洲5最新开奖结果:Tom Pidcock (Q36.5 Pro Cycling), the tyre pressure sensors immediately caused a flurry of excitement ꦍacross the cycling tech world.

With the concurrent 168澳洲5最新开奖结果:emeꦯrgence of self-adjusting tyre systems at this year's Spring Classics, it was easy for the cycling world's collective imagination to run wild. However, 168澳洲5最新开奖结果:a patent filed by SRAM in 2024 shed light on the internal working of the rim – essentially a natural evolu💞tion from Zipp's TyreWiz system.

Zipp has now revealed all details around the new wheelset, with the Zipp 353 and 303 becoming the very firstꦏ AXS-connected wheelsets, bringing the wheels ဣinto SRAM's suite of electronic systems with in-wheel tyre pressure monitoring integrated into the rim itself.

The AXS wheel sensor, on the surface, functions much as we'd expect: flashing a green light when the tyre is set to the correct pressure range and red when iꦓt falls outside of that. However, there has bee🍃n impressive integration into SRAM's wider ecosystem below the surface.

The system goes beyond binary red and green, and can be integrated with Hammerhead, Wahoo, and Garmin head units to provide real-time tyre pressure monitoring. In the case of the Hammerhead, thatܫ is displayed by two circles with live pressures and a green or red indicator to reflect whether it's in the correct range. The system is also heavily integrated with SRAM's AXS app, providing metrics and user guidance on the tyre pressure system.

Cyclingnews was in Indianapolis for the 🅷global launch event, where Zipp product manager Nathan Schickel explained the holistic th𒁃eory behind the AXS sensor. 

"When you get your wheel with a Zipp AXS wheel sensor you'll be able to add it to your AXS app, find your recommended tyre, learn how to install it – install the t🍰yre based on an in-app animation, find your best tyre pressure, set it and then that will then help feed that information to your head unit," he explained.

"Not only do you set your target pressure, but you set your variability range," Shickel continued. "If your tyre pressure falls out of that ♏chosen range, then not only will the blinking light when your wheel is stat🍒ionary go from flashing green to flashing red, but the display on your Hammerhead screen will go from green to red."

The unit itself is not entirely revolutionary but sta꧋nds on the shoulders of the Quarq TyreWiz, owned 🍒by Zipp-parent company SRAM. Like the TyreWiz 2.0, this unit integrates the entire valve stem into the sensor system and uses a small gap in the stem itself to monitor live pressure readings.

The ♚system is conceived as a fully tubeless setup, with Zipp shipping a custom tubeless sealant syringe that preserves the sensor from damage during setup.

A key step forward, tho🔯ugh, is the introduction of a TPU tube that is fully compatible with the system. That means that if a puncture isn't repairable with sealant or a plug, where previously a tube could be inserted but at the cost of live pressure readings, now that functionality is preserved. And of course, there are pl💝enty of riders who simply prefer TPU tubes over tubeless and will default to this setup.

The unit is powered by a 2032 coin cell ꦉbattery, which Zipp cꦅlaimed offers 400 riding days' worth of battery life.

E♕lsewhere, there are changes in both the 353, 3𓄧03 and wider Zipp range.

Wheelset redesigns and ZR1 SL hubset

While the AXS tyre sensor is the main event,ཧ the 353 NSW and 303 SW have also had an upgrade across ꦚtheir wider design.

A revised carbon layup has ▨seen wheelsets improve impact strength without weight increases, with Zipp claiming a 10% bump in strength for the 303, and a 16% jump in rim impact strength for the 353. 

The 303 SW is technically a first iteration of♋ the 'SW' moniker, but compared to the pre-existing 303 has undergone a refinement of its rim shape to help protect the tyre from pinch flat♒s.

A central upgrade across the range has been Zipp's ZR1 SL hubset foܫr the NSW wheelsets. Modelled on the existing ZR1, the SL has trimmed🎉 down on weight, coming in at 304g with ceramic bearings, alongside 66 points of engagement.

Zipp's 858 NSW has also undergone a minor upgrade, albeit largely focused on a 30g weight saving from switching in the ZR1 SL hubset. With tyre pressure optimisation surely a big lure for triathletes watching their watts and neurotic about a slow flat, we expect that the 858 may soon undergo a bigger update that i🅷ntegrates the AXS wheel sensor.

Zipp introduces aero tyres alongside a big leap in wider tyres trend

Zipp's collaboration with Goodyear moved into full swing last year with the Goodyear Vector R Z30 SW tyres, designed to be paired with the 353 NSW wheelset. The wider Vector R Z35 SW was paired with the 303. The next step in the partnership is a substantial one, though, with the Goodyear Eagle F1 R Z29 Aero tyre entering the territory of cust🀅om aerodynamic integration with Zipp's wheels.

The tyres use Aero Lip technology, which effectively blends the tyre-rim transition to create a smooth profile to the side of the wheel. Those with an obsessive memory of bike tech may remember the Mavic Cosmic CXR80 aero wheels, which employed a similar design concept, using aꦅn integrated plastic insert to cover the gap between the tyre edge and the rim wall. These are much subtler, simpler and more smartly integrated, but play to the same logic of changing the overall shape of the wheel. 

"With new techn𓆏ology from Goodyear, we created an aero lip that blends the tyre into the rim and allows us to run a slightly wider section with for the same aer൲odynamics of a slightly narrower tyre," explained Schickel.

Weighing in at a svelte 270g, the🅠y're designed to measure 29mm on Zipp’s 23mm TSS (Tubeless Straight Side) - aka hookless - rim. That ma𒁃kes them most suited to pairing with Zipp’s 404 and 454 wheels, which underwent a similar update to the 858 with a hub switchout. 

For us, the more interesting fruits of the Goodyear-Zipp partnersওhip are the ൲Goodyear Vector R XPLR.

If you're a regular visitor to Cyclingnews, you will be familiar with our now-infamous tyre width test. Within it, we unearthed that 40mm tyres 🍸were faster for almost all road riding scenarios.

Zipp is a brand that is very much in the same school of thought, and the Goodyear Vector R XPLR is designed to measure 40mm on Zipp’s 32mm TSS rim✤, notably the rim used onౠ the 303 XPLR. 

"This is, personally, one📖 of my favourite things," Schickel said. "It is a road tyre built specifically for the 303 XPLR wheel. What we realised is that larꦜger tyres on the road can pay off for a lot of riders. 

"It has a 40mm sect꧋ion width. It's designed around that Vector R casing. So it's a durable casing, but it still rolls very fast. It has a very lightweight tread cap."

For those interested in wide tyre gains on the road, the Goodyear Vector R XPLR will becom🌳e one of the few 40mm tyres on the market, along with the Pirelli P-Zero Race 40mm and Cinturato Evo, with a design which is suited to road riding as w🉐ell as gravel.

Zipp, encouragingly, doesn't show any sign of slowin෴g down on its wider-is-better trend. With even the road-focused 303 SW optimised around a 30-35mm tyre width, we could believe that the brand may soon seek to normalise road tyres closer to 40mm in width.

We'll be testing the 353 NSW wheels and the new Goodyear Vector R XPLR tyres on Cyclingnews in the weeks to come. Stay tuned.
