Ask Josh Anything #003

We didn't necessarily intend for it to turn out this way, but this episode of Marginal Gains' "Ask Josh Anything" is a wheels, rims, tubes, and tires question extravaganza. We also find time to discuss the Silca Hiro chuck's origin story, whether testing how aero helmets are in a lab setting has real value, and exactly how much impact on your ride those gatorskins are having.
