This episode of the Marginal Gains Cycling Podcast dives deep into the ongoing debate around road wheel hookless technology, sparked by Josh's critical stance on the subject. At Sea Otter 2026, the hosts interviewed representatives from three major wheel brands—Envy, Kadex, and Mavic—to explore their philosophies, engineering decisions, and real-world experiences with hookless road wheels. Envy, a pioneer in road hookless design, defends its approach by emphasizing durability, precise manufacturing, and the role of tire quality in safety. They introduced the 4.5 Pro, a hybrid wheel that blends hookless aesthetics with a functional hook bead for improved pressure tolerance and performance. Kadex, a Giant-owned brand, champions hookless as a performance-driven choice, highlighting its proprietary carbon spoke technology and rigorous tire qualification protocols. They argue that rim design is not the primary failure point—tire bead strength and proper inflation are key. Mavic, a heritage brand undergoing a U.S. revival, maintains a firm stance on hooked rims for road use, citing proven reliability, the importance of ETRTO standards, and the need for added retention under high pressure. The episode reveals a nuanced industry landscape where safety, engineering, and rider behavior are all critical factors. Despite public skepticism and high-profile blow-offs, the consensus among experts is that the real issue lies not in hookless vs. hooked design, but in the quality of the entire wheel-tire system and user education. The episode also touches on broader trends, including the rise of wider tires (32mm), the importance of tire volume over pressure, and the growing role of tire-wheel integration. Envy and Kadex both emphasize that modern tubeless tires are capable of far exceeding ETRTO pressure limits, making the fear of blow-offs largely unfounded when proper components are used. Mavic stresses the value of standards and system integrity. The hosts conclude that the future of road wheels isn't about choosing one side over the other, but about understanding the full ecosystem—rim, tire, pressure, and rider behavior. The episode sets the stage for a follow-up 'Ask Josh Anything' segment, inviting listeners to engage with the debate.
Hookless road wheels are not inherently unsafe; the real risk comes from poor tire quality, improper inflation, or rim damage—not the design itself.
Modern tubeless tires are engineered to handle pressures far beyond ETRTO limits (up to 140 psi in testing), making the '72.5 psi' rule outdated for quality setups.
Tire volume matters more than pressure: a 32mm tire at 70 psi provides the same contact patch and ride feel as a 25mm tire at 80 psi.
The key to safe tubeless performance is system compatibility—rim, tire, and pressure must all be within spec and matched properly.
Brands like Envy and Kadex are innovating in manufacturing and tire partnerships to ensure reliability, while Mavic remains committed to hooked rims for road use.

Opening: Sea Otter 2026 Recap & Episode Focus
The episode opens with a brief recap of Sea Otter 2026, highlighting Silca's presence, Shimano's massive compound, and the Marginal Gains team's extensive interviews. The focus shifts to the central debate: road wheel hookless technology, with a promise to hear from three major brands.
Envy: Pogacar’s Influence & the 4.5 Pro Hybrid Wheel
“The 4.5 Pro is a full hooked bead... it is, you know, if you look at the specification defined by ETRTO we're at the lower end of that range as far as like the width of that hooked bead but it is as far as the standard is concerned a hook bead.”
Envy on Hookless Safety & Tire Quality
“In our testing, we have had to do much less of it in the recent years, but we very regularly see tires that basically achieve 140 psi before they come off a rim.”
Kadex: The Case for Hookless & Tire-Wheel Integration
“If you look at ETRTO standards it's driven by the tire industry. It's not driven by the wheel industry. It is a tire... I'm gonna call it a standard or a guideline.”
Kadex on Aerodynamics, Tire Shape & System Efficiency
“Once we put our aero tire on other people's wheels, the gain in aerodynamics for their wheel went up. Probably shouldn't be saying that because then people just buy my tires.”
“In our testing, we have had to do much less of it in the recent years, but we very regularly see tires that basically achieve 140 psi before they come off a rim.”
