Zipp 404S Wheelset Review: Performance and Practicality at a Competitive Price
Nutrition · Words by James Miller · Released
The Zipp 404S wheelset offers solid performance for road cycling enthusiasts at a lower price point, but its hookless design and weight might be drawbacks.
The Zipp 404S wheelset replaces the earlier 303S model, introducing a 50mm rim depth tailored for modern road cycling. According to Zipp, this new design is efficient, reportedly saving about two watts compared to its predecessor. Retailing at $1,300 for the pair, the 404S wheels provide a cost-effective alternative to Zipp's flagship models while incorporating a lifetime warranty, a feature not commonly found in mid-range wheelsets.
Initial Impressions
Over the course of two months, I tested the Zipp 404S on my steel Ritchey Road Logic, culminating in roughly 800 miles of varied terrain. The overall experience with the wheels was positive; they feel stable and reliable, performing admirably on both flat roads and during climbs. The acceleration was commendable once the wheels were in motion, and they handled windy conditions better than I anticipated. Essentially, Zipp has created a wheelset that ticks a lot of boxes and is likely to be the stock option on many bikes featuring SRAM components.
Ride Quality and Handling
On the road, the 404S wheels blend seamlessly into the riding experience. The comfort level is high without inviting excessive harshness, providing a reassuringly solid feeling as you reach speed. In terms of crosswind handling, they exhibit commendable stability, placing them a step below perhaps the elite Roval Rapide CLX III but still managing well on blustery days.
However, one notable difference emerged when tackling steep climbs. I found the weight of these wheels became more apparent during these efforts. While they don’t feel sluggish during routine riding, it’s clear that lighter aero wheelsets can offer a more responsive feel, especially when accelerating from a standstill or on climbs.
Design and Specifications
The Zipp 404S utilizes a Tubeless Straight Side design, which means navigating tire compatibility is crucial. Zipp recommends tires in the 28 to 39mm range, with optimization for 28 to 29mm sizes, yielding better aerodynamic performance. Notably, the maximum pressure allowance is 73 psi, which drops down to 65 psi for 30 or 32mm tires based on ETRTO guidelines. Riders accustomed to wider tires at lower pressures might find this less of a concern, but the ongoing industry debate about hookless versus hooked designs cannot be overlooked.
The Hookless Factor
The hookless rim design poses certain limitations. Many cyclists in 2026 may prefer a hooked interface due to the flexibility it offers in terms of tire pressure and compatibility options. Zipp faces criticism for staying committed to this design format, especially when competitors like ENVE have adjusted to incorporate a “mini hook” for added compatibility. This could indicate a shift in consumer preference, and there are signs that Zipp may eventually revisit its design approach to include a hooked option.
Weight Considerations
Weighing in at approximately 1,537 grams with an XDR freehub, tape, and valves, the 404S is notably heavier than some comparable models. For example, HUNT’s 50 Carbon Disc wheels are listed at around 1,464 grams and retail for slightly less. Conversely, Shimano’s Ultegra C50, another competitor, comes with a higher price point at $1,570 but features a hooked rim, which may appeal to some riders.
The challenge for Zipp lies in the competitive landscape, where alternatives like Light Bicycle offer comparable or lighter wheelsets at similar or lower prices. Light Bicycle's builds claim weights starting significantly lower, allowing for a broader array of options for the discerning cyclist.
Warranty and Value
What sets the 404S apart, however, is its comprehensive lifetime warranty, extending beyond just manufacturing defects to include damages from normal wear and tear during intended use. This policy can be particularly reassuring for riders who prioritize reliability alongside performance.
In summary, the Zipp 404S wheelset stands out as a solid choice for those seeking a reputable brand and dependable performance at a reasonable price. The advantages of stability, a pleasant riding experience, and a lifetime warranty counterbalance the drawbacks of weight and the limitations associated with a hookless design. Riders weighing these factors should consider their individual needs and riding style when deciding if the 404S is the right fit for them.
