This is an Engineer's episode if there ever was one. Josh talks to James Woolcock of Bastion cycles, a maker of custom frames, or as the site puts it, "Bespoke Luxury Performance Bicycles." As you would expect, these bikes come with a significant price tag, but there's a lot of custom engineering based on a customer’s wants and needs going into each of their highly unique, high-performance bikes. Even if you're not in the market for an ultra-high-end bike, however, you'll enjoy the conversation between these two marginal gainers with engineering degrees.
