AJA 24: Making Hydration Aero, Carbon Wheel Failures, & Wireless Braking


Josh answers a batch of listener questions, from the extremely practical to the fascinatingly hypothetical. Are pros flatting more than they used to? Has the balance between strong and light swung too far toward light? How do you make your hydration as aero as possible? What air pressure should be used for the back wheels on a competitive trike? And how good would electronic / wireless brakes have to be before you could trust them? We get into all this and more in this Ask Josh Anything episode of Marginal Gains!

    Curious about the trike pressure recommendations, as using the silca tyre pressure calculator for my children I’ve noted higher pressures recommended than expected becuase I was expecting that 1/2 the load →1/2 the pressure. But the recommendation is only to drop ~10psi going from 90kg to 45kg. So for the trike why should he not be splitting the rear load across the 2 wheels and putting that in the calculator, instead of halving the pressure?
