Road Hookless Wheels: Josh Poertner Explains the “SCAM?” That Went Viral in Cycling Circles

▬▬▬▬ Video Overview ▬▬▬▬ Are road hookless wheels safe? In this video, SILCA’s Josh Poertner—a former Chairman of the Bicycle Wheel Technical Committee (Aug 2012 – Sep 2013)—explains why he believes hookless road rims offer no improved aerodynamic benefit, carry tubeless blow-off risks, and push the limits of ETRTO safety margins. He also responds to the cycling media coverage following his Marginal Gains Podcast question about whether hookless road rims are considered a “scam.” Recent discussions within the cycling community have centered around Josh’s claims and question. Drawing on decades of engineering experience and leadership in wheel standards, Josh argues that hookless road rims offer no improved aerodynamic benefit and present potential safety risks—primarily due to a lack of margin for error with tire pressure. Josh’s claims (road use): • No Improved Aerodynamic Benefit: No measurable real-world aero gains over hooked rims; in some cases, aero performance is worse. • Potential Safety Risks: Tire blow-off risk at pressures as low as 78–80 PSI, with narrow safety margins and tire/rim compatibility concerns. In this video, Josh also covers: • The tire width vs. rim width rule (Rule of 105, ETRTO guidelines) and why it matters • The need for at least a 5mm tire-to-internal-width gap for safer hookless road use situations • Tire sizing inconsistencies between brands that complicate safe fitment decisions by consumers If you’re researching: road hookless rim safety • tubeless tire blow-off • hookless vs hooked rims • ETRTO road limits • Rule of 105 aero • road tubeless safety • bicycle rim standards Watch the full Marginal Gains Podcast episode where Josh made the attention-getting statement here: https://silca.cc/blogs/marginalgains/...
