It seems everything cycling-related is fetching inordinate amounts of money on the used market these days, and so we figured it was a good time to trade in Caley and Zach for a special guest host: Dan Cavallari, former tech editor for Velonews and now freelancer extraordinaire.

Dan covered Unbound Gravel for CyclingTips this year, so it only seemed right for James and Dave to run through all the interesting gravel tech with him.

Wondering about tire inserts? Tire sizes and pressure? Handlebar setups? Gearing? We go through it all, and bookend it with the usual round-up of tech news and Ask a Mechanic questions. And don’t worry, Caley and Zach will be back next week — probably. Maybe.
