AJA #43: CRR/CDA and Hookless plus The Magnus Effect
Friday, 11 July, 2025
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. 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. 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.
