Bikes, Journalism, and Integrity with CyclingTips' James Huang

James Huang, Global Technical Editor of CyclingTips, is one of the most-trusted cycling journalists in the industry today — and for good reason. He brings knowledge, experience, humor, and integrity to everything he covers. In this episode, Josh and James have a great, wide-ranging conversation — from their similar histories in getting into the cycling industry, to how the cycling world has changed, to the relationship of cycling journalism and product manufacturers, and much more.

    Not a question on your podcast, but one I heard from a leading US publication with their long-serving technical editor. Talking about choosing the proper tire pressure, he introduced the concept of hoop stress. Though the discussion was confusing, what I got out of it is that hoop stress is greater than the force from the pressurized air in the tire and so should be taken into account when looking at the behavior of the tire. As I understood it, he said that the effective pressure in the tire is not the gauge pressure, but the hoop stress in the casing. I can understand why hoop stress needs to be considered when designing the casing to make sure it is strong enough and won’t split, but I don’t see how it would affect the spring rate of the tire. Could someone explain? Thank you.

    Hi guys,

    Couple of months ago there was a bit of controversy over Youtube where an engineer was bashing on any and everyone in the cycling industry about how wrong they all were. Controversies aside, one takeaway that made a bit of sense was that tests should always be done against turbulent, not laminar, flows. Hence my questions for Josh:

    - Considering this engineer is right and turbulent flows make more sense in the road, while laminar only makes sense in the velodrome, how can we test using turbulent flows in wind tunnels?

    - Since turbulent flows are unpredictable in nature, how can we compare products?

    - Are differences in behaviour between turbulent and laminar flows enough in cycling that a good product in a wind tunnel would be terrible in real life?

    - Anything else I am missing?

    Thanks in advance for the answer and great job with the podcast.
