1 rich Libsyn https://www.libsyn.com 90 600 We take a look at what has become a dilemma for some Marginal Gains seekers and that is optimizing aero, rolling resistance on a tubeless, hookless rim. Josh has an admittedly unpopular take on the subject.&amp;nbsp; We also get into the aerodymanic idea known as the Magnus Effect. The principle says that a spinning object will develop unequal pressure on either side as it moves throught air. Josh expains how -- if at all -- the Magnus Effect, affects that rotating thing we love; the bicycle wheel.&amp;nbsp; We also have questions on hot waxing in a vacum oven, the aero cost of external cables, and what is kind of a Silca product shocker: it's Ultimate Shock Pump.&amp;nbsp;&amp;nbsp; Marginal Gains Cycling Podcast, Presented by Silca http://marginalgainspodcast.cc <iframe title="Libsyn Player" style="border: none" src="//html5-player.libsyn.com/embed/episode/id/37381200/height/90/theme/custom/thumbnail/yes/direction/forward/render-playlist/no/custom-color/88AA3C/" height="90" width="600" scrolling="no" allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen></iframe> https://assets.libsyn.com/secure/item/37381200
