There are wheels you fit to save weight. Others to completely change a bike’s behavior. The Zipp 454 NSW Tubeless clearly belong to the latter.
It has been almost a year that this pair has been on different bikes, with more than 8,000 km on the clock. On paper, it ticks all the boxes of Zipp’s most exclusive know-how: hookless carbon rim, wavy Sawtooth profile, dimpled surface, ZR1 SL hubs with ceramic bearings, around 1,400 g and a variable depth between 53 and 58 mm.
Highlights:
- Good crosswind stability
- Very easy to hold a high speed
- Low weight for wheels this deep
To improve
- Very high retail price
- Early marking/corrosion observed
But a wheelset at nearly €4,000 MSRP cannot just be pretty, light and high-tech. At this level, it must deliver something clear on the road. And that is precisely where the 454 NSW get interesting.
A spectacular rim, but not just for style
The first thing that jumps out is obviously this sawtooth rim. Zipp calls it Sawtooth, with Hyperfoil shapes and a HexFin ABLC surface, in other words the small dimples typical of the American brand.
It would be easy to reduce this to an aesthetic choice. That would be too hasty. On the road, this shape mainly helps manage crosswinds. And in a region like the Vendée, where gusts from the coast are frequent, that is not just a theoretical detail.
Fitted to an aero bike like the Van Rysel RCR-F, the 454 NSW even give the feeling of making the bike more composed when the wind picks up. These are still deep rims, so do not expect total neutrality, but the stability is really convincing for this level of depth.
Hookless: effective, but you must follow the rules
The 454 NSW are offered with a hookless rim, i.e., without a bead hook. It is an increasingly common choice at Zipp, also found on all of their gravel models, such as the Zipp 303 XPLR S.
The benefit is known: a cleaner transition between tire and rim, potentially lighter manufacturing, and a more coherent aerodynamic logic with modern tires used at lower pressure. But hookless also demands real discipline.
You must use compatible tires, respect maximum pressures and not consider this rim as a universal wheel you can mount anything on. Zipp states compatibility with ISO/TSS tubeless tires between 28 and 35 mm, with a maximum pressure of 5 bar.
With its 23 mm internal width, the rim could technically accept fairly generous sections. But in practice, these wheels are most relevant with 28 to 32 mm tires. That is where they deliver the best balance of efficiency, volume, aerodynamics and handling.
I notably mounted the new Continental GP 5000 S TR in 35 mm currently under test. The setup works, but you get a really big balloon. It is not incoherent, but it is not where the wheel feels most natural.
Tubeless setup: simple, clean, reassuring
On this point, the Zipp 454 NSW live up to their positioning. Tubeless setup is a breeze, sealing is very good, and pressure retention over time remains decent.
Valves are supplied with the wheels, the finish is clean, the accessories inspire confidence. At this price level, it is expected, but still worth highlighting.
Overall build quality is also in line with what we expect from Zipp. The ZR1 SL hub with ceramic bearings spins very well, the freehub remains audible without being intrusive, in the vein of the brand’s other products.
On the road: not the most explosive, but formidable once up to speed
Let us be clear: the Zipp 454 NSW are not the snappiest wheels when accelerating. If your priority is to attack every thirty seconds, race criteriums, urban circuits or very stop-and-go rides, they are probably not the most suitable wheels.
Their strength lies elsewhere. Once up to speed, they give that very pleasant impression of holding speed with ease. They flourish at cruising speed, on fast sections, long straights, false flats and rides where you aim to ride smoothly, for a long time, efficiently.
On an aerodynamic bike, the pairing works particularly well. The 454 NSW seem made to elevate an already fast machine rather than to transform a lightweight bike.
Climbing: better than expected on steady efforts
At around 1,400 g, the 454 NSW remain relatively light given their depth. They are not mountain wheels, but they also do not feel like you are dragging an anchor.
In the rolling cols of recent weeks, they proved very pleasant on steady climbs. As long as the effort remains measured, with a stable cadence and few violent surges, they do not become a handicap.
Conversely, on very irregular gradients or stretches where you must constantly slow and re-accelerate, their character shows more clearly. They prefer continuity to explosiveness. That is not a flaw in itself, but it is an important selection criterion.
Watchpoint: hubs in salty air
After more than 8,000 km, the rolling qualities are still there. The wheels have not lost their smoothness, which is rather reassuring for such a high-end pair.
One point is worth noting, however. The machining on the hubs, at the spoke insertions, shows wear marks that look like corrosion. The detail is all the more surprising since these wheels have seen very little rain and were carefully cleaned after rides.
Context likely plays a role: salty coastal air in the Vendée can attack certain components, even without heavy rain use. So we should not draw a definitive conclusion about overall hub durability, but at this price level, this point deserves monitoring. I have not encountered this problem on other wheels from the brand such as the Zipp Firecrest, which were treated far more harshly.
A very high price, but sometimes more accessible in practice
The recommended retail price for the pair is around €4,000, depending on configurations and markets. That is huge. Even for high-end carbon wheels, even with ceramic bearings, even with real aerodynamic research.
Fortunately, the Zipp 454 NSW can fairly easily be found at lower prices, often around €2,700. It is still a considerable budget, but you then enter a zone more comparable to other premium references like the DT Swiss ARC 1100.
Another interesting point: these wheels sometimes appear as original equipment on certain very high-end bikes. In that case, they are not always priced at their full standalone rate within the complete bike price, which can make them more accessible than a separate purchase.
This is probably one of the smartest ways to acquire them: not as an impulse purchase at list price, but as a true upgrade integrated into an already coherent bike.
Who are they for?
The Zipp 454 NSW are first and foremost for rouleurs – riders who like to hold a high speed, ride long, optimize an aero bike and enjoy a stable, fast, confidence-inspiring wheel.
They will suit a rider who mainly rides on the road, with 28 to 32 mm tires, tubeless, on fast, rolling or wind-exposed routes. They can also work on long distances, provided you accept their more inert character in repeated accelerations.
Conversely, this is not the pair to recommend first for an ultralight mountain-focused bike, for very punchy routes or for allroad use. The internal width may tempt you to go wider on tires, but the DNA of these wheels is clearly road.
My verdict on these Zipp wheels
The Zipp 454 NSW are among the most beautiful wheelsets I have had the chance to ride. Not just because they are visually spectacular, but because they have real character: fast, stable, very pleasant once up to speed, and particularly coherent on an aerodynamic bike.
They do not try to do it all. They are not the most explosive, not the most logical for pure mountain riding, not the most rational financially. But for a rouleur who wants a very high-end pair able to hold speed easily and remain reassuring in the wind, they have something really special.
At list price, they are still hard to justify. At a discounted rate or as original equipment on a premium bike, they become much more compelling.
