On one end of this week’s roundtable discussion is Josh Poertner, owner of Silca and former technical director at Zipp. Armed with years of experience helping the world’s most elite teams and racers go faster over a wide range of terrain,Poertner has learned far more about wheel-and-tire setups than any of us knew was possible. Sitting opposite Poertner is Jan Heine, publisher of Bicycle Quarterly and head of Compass Bicycles, and the man who is largely credited for singlehandedly popularizing the grassroots wide-and-low road tire movement five years ago.
Can’t quite allow yourself to believe that a 30mm tire at 70psi might be faster than a 23mm one at 100psi? Okay, but do yourself a favor and have a listen to what Poertner and Heine say about it — and keep an open mind, because what you feel, and what the numbers tell you, don’t always go hand in hand.
