The 88mm Advantage: Why Deep Rear Wheels Are Dominating 2024’s Triathlon Courses
Rethinking Speed in Modern Triathlon Racing
As the 2024 triathlon season reaches its peak, from the legendary IRONMAN Kona World Championship to Challenge Roth and IRONMAN Europe Series, one trend has become unmistakably clear: more and more elite athletes are running deep-section rear wheels — especially the 88mm Carbon Rims — as their secret weapon for time savings and aerodynamic supremacy.
While front wheels have largely stabilized at 60–70mm depths for better crosswind control, the rear wheel scene has evolved dramatically. Riders are now confidently opting for 88mm deep section rear wheels, claiming both measurable aerodynamic gains and greater speed consistency.
According to data from several aerodynamic analysis platforms, in a 40km triathlon cycling segment, an athlete using a 60mm front wheel paired with an 88mm rear wheel can save 30–60 seconds over the same rider using 60mm front and rear wheels — at equal power output. For those chasing Kona qualification or podium finishes, this margin can be decisive.
Why 88mm Carbon Rims Are Redefining the Triathlon Standard
1. Aerodynamics Above All
Triathlon races are defined by sustained, steady speeds and minimal pack riding. This makes aerodynamics the single most critical performance factor. The rear wheel, positioned behind the rider’s body and largely shielded from crosswinds, can safely push aerodynamic optimization to the extreme.
The 88mm Carbon Rim takes advantage of this principle. Its deep-section aero profile maximizes airflow smoothness and minimizes drag — especially in yaw angles between 5°–15°, which are most common in real-world racing. Riders experience not only higher top-end speeds but also easier speed maintenance at the same wattage.
2. Why Carbon Tubular Rims Still Matter in 2024
Though tubeless systems have gained mainstream popularity, tubular rims remain the gold standard among many elite triathletes for specific reasons:
| Feature | Tubular Rim Advantage | Triathlon Benefit |
|---|---|---|
| Rolling Resistance | Lowest rolling resistance among all tire systems | Saves watts over long distances |
| Ride Comfort | Smoother, more responsive feel | Reduces muscle fatigue before the run segment |
| Puncture Behavior | Air pressure drops gradually after puncture | Lower risk of DNF; more control time |
| Weight | Lighter than clincher/tubeless setups | Better acceleration and hill performance |
This makes the Carbon Tubular Rim configuration a top choice for serious triathletes who prioritize reliability and efficiency in long-course races.
3. The “Golden Ratio” of 88mm Depth
Why 88mm — and not 80mm or 90mm?
Testing in both wind tunnels and CFD (Computational Fluid Dynamics) simulations reveals that 88mm strikes the optimal balance between aerodynamic drag reduction and rotational inertia.
On flat or slightly rolling terrain, the 88mm profile offers up to 6–8% drag reduction compared to 60mm rims.
The U-shaped cross-section stabilizes handling in side winds up to 15°, maintaining confidence in real-world triathlon conditions.
Its higher moment of inertia supports sustained momentum — perfect for the steady, non-stop effort required in long-distance triathlons.

FAQ: Everything You Need to Know About 88mm Carbon Rims
Q1: Are 88mm carbon rims difficult to control in crosswinds?
A: Not for the rear wheel. The rider’s body and frame shield the rear wheel, making it minimally affected by crosswinds. You can enjoy full aerodynamic benefits without handling compromise.
Q2: Why choose a tubular rim when tubeless is available?
A: Tubulars still provide the best combination of lightweight construction, rolling efficiency, and gradual deflation safety — ideal for long-distance triathlon events.
Q3: Are the 88mm rims compatible with disc brakes?
A: Yes, the Monsoon 88 TR is available in both rim-brake and disc-brake versions to fit all modern triathlon frames.
Q4: Is there a noticeable difference between 80mm and 88mm?
A: Absolutely. While the difference seems small, the 88mm profile’s refined aerodynamics and deeper airflow optimization can yield measurable time savings at race speeds above 35 km/h.
Conclusion: The 88mm Era Has Arrived
For triathletes aiming to convert every watt into pure forward motion, investing in an 88mm Carbon Rims Aero Triathlon Rear Wheel might be the most cost-effective performance upgrade available.
The Monsoon 88 TR from TRIPS isn’t just another wheel — it’s a precision-engineered speed engine, designed through aerodynamic science and built with racing passion.
