30% More Efficient? The Math Behind Aero vs. Steel

We dug into the data to find out. After a 20-minute head-to-head test between a modern aero setup and a classic steel bike, the results were staggering: The aero setup was 30% more efficient, requiring just 221 watts to outpace a rider pushing 288 watts. In this episode, the Velo tech team breaks down the physics of why "Weight Weenie" upgrades fail where aerodynamics succeed, and how you can find these same "free" watts on your next ride. Also in this episode: The Vingegaard Incident: A deep dive into Jonas Vingegaard’s recent crash in Spain involving a "stalker" fan and the reality of pro/fan interactions on open roads. Gravel Suspension Shootout: Is the Lauf leaf-spring fork actually better than the Cane Creek Invert? We answer listener Q&A about upgrading the Salsa Cutthroat. The Leadville Ban: The crew debates LifeTime’s decision to ban drop bars at the Leadville Trail 100 MTB. Tech Hot Takes: A defense of the critical take on Pinarello’s new Grevil MX mountain bike conversion.
