Zipp is back with a tech-loaded refresh to its aero carbon NSW and SW road wheel lineup—now with integrated tire pressure monitoring sensors. Remember those wheels the World Tour teams were rolling in the classics with the TPMS pressure sensor built in? Well, here they are, just in time for the summer races. Zipp’s updated 353 NSW and 303 SW, now come fully connected via SRAM AXS wireless connectivity, bringing real-time tire pressure monitoring straight to your bars (and phone).
Zipp 353 NSW & 303 SW aero carbon wheels integrate TPMS
Like many launches, this one comes with more than a few extra updates beyond that Zipp TPMS-equipped wheel headline. The most notable are new tires from Goodyear that work with the updated wheels. Then, new Zipp ZR1 SL hubs, 30g lighter than the ZR1 hubset, will now be sold as standalone components, as well. Lastly, the deep dish 454 & 858 NSW wheels also get some of their own updates like ceramic bearings and weight savings.
This is a long one.
So, let’s start at the top with the new Zipp 353 NSW.
Zipp 353 NSW: Tech-Heavy and Feather-Light
The 353 NSW is Zipp’s halo road wheelset—and now it talks to your AXS app. A tucked-in integrated AXS wheel sensor gives you in-the-moment tire pressure data, so you can tune performance on the fly without strapping a hockey puck to your valve stem. Think of it as direct-to-your-hub TPMS intelligence for dialing tire pressure with pro-level accuracy.
At a claimed 1310g, this mid-depth wheelset is pretty light for something stiff and strong with a pressure sensor. Zipp’s latest carbon layup delivers a 16% bump in impact strength. Paired with the Sawtooth rim profile varying from 35-40mm depth, the 353 NSW balances climbing weight with aero chops and crosswind stability. It’s all anchored by the newly tweaked ZR1 SL hubset, with 66 points of engagement and silky ceramic bearings.
The rim is optimized for 30mm rubber, and Zipp’s collaboration with Goodyear in the Fitment Series makes picking the perfect match even easier. Don’t toss these on your gravel rig, though—they’re strictly for on-tarmac duty.
353 NSW Highlights
- 1310g for the set
- Tubeless-only, 25mm internal width
- Hookless TSS rim profile
- 30mm optimized tire width
- new ZR1 SL hub with ceramic bearings
- Real-time tire pressure tracking via integrated SRAM AXS TPMS sensor
- $3350 for the front & rear pair
Zipp 303 SW: Road, Gravel & Cobble-Crusher
Next up: the 303 SW—Zipp’s road-to-gravel crossover wheelset. It carries the same AXS integration and hookless tubeless rim tech but focuses on all-road versatility. With a 40mm deep rim and a 25mm internal width, the 303 SW is tuned for 30-35mm wide tires, making it ideal for rougher tarmac, endurance events, and fast gravel.
Like the 353, the 303 SW got a strength boost—up 10% in impact resistance thanks to revised carbon layups. A wider rim footprint and lowered tire pressures improves rolling resistance efficiency and reduces fatigue. More speed, less shake.
And while the ZR1 hub here skips the ceramics in favor of stainless steel bearings, it’s still snappy and serviceable, with the same modular end caps and classic J-bend spoke compatibility.
303 SW Highlights
- 1440g for the set
- Hookless TSS tubeless rim
- 25mm internal width, 40mm depth
- ZR1 hubset with stainless steel bearings
- Real-time tire pressure tracking via integrated SRAM AXS TPMS sensor
- $2200 for the front & rear pair
Updates to the Deep Aero Big Guns: 454 & 858 NSW
Zipp’s top-tier deep section aero wheels—454 NSW and 858 NSW—also get a touch-up. Both wheelsets now feature the lighter ZR1 SL rear hub (30g shaved off), ceramic bearings, and the signature 66 POE engagement. Rim profiles stay deep and wavy:
- 454 NSW: 53/58mm Sawtooth profile, optimized for 28mm tires.
- 858 NSW: Massive 82/85mm rim depth, ideal for triathlon and time trials. Despite the depth, the weight is kept to 1500g thanks to TSE efficiency and hookless tubeless construction.
ZR1 SL Hubset: Now Also Sold Separately
Want a piece of the speed pie without springing for complete NSW wheels? The ZR1 SL hubset is now available on its own. It’s lighter, stiffer, and still approved for light-assist e-bike use (motors up to 60Nm). Available with ceramic or carbon steel bearings and a range of driver bodies—including XDR, HG11, MicroSpline, and N3W.
Tire Time: Fitment Series by Goodyear
What good is a killer wheelset without the right rubber? Zipp teamed up with Goodyear for the Fitment Series, dialing in tires to perfectly match each wheel’s optimized width and shape.
Goodyear Eagle F1 R Z29 Aero (29mm)—Made to max out aero performance on Zipp’s 23mm internal rims (like the 404/454). At just 270g, this road racing tire features a 180tpi casing and Zipp-specific Aero Lip design for drag-cutting seamlessness from rim to tire.
Goodyear Vector R XPLR (40mm)—Built for the 303 XPLR, this tire pairs a supple 120tpi casing with dual puncture protection for all-road speed and control. It is tubeless-ready, 440g at such a big volume like this, and promises much more puncture protection than our puncture-riddled test tire back at the original 303 XPLR launch.
Reporting Back Soon – No First Impressions, Just Yet
There is much to digest here. And we’re still waiting for the product to arrive for our own first impressions, especially how seamlessly TPMS will integrate into our everyday riding, perhaps as we’ve become accustomed to in cars these days. Check back for a full review of the Goodyear Vector R XPLR to see how that puncture protection fares, and for whatever else new tech we get our hands on from this launch.
