Roval and Specialized appear to be returning to road tubeless after last year\u2019s curious non-tubeless tubeless wheel launch, we question the merits of Ratio Technology\u2019s latest 12-speed conversion kit, and \u2014 no surprise \u2014 Shimano made a heck of a lot of money last year.\nBut we also now have more concrete proof that the Covid-fueled bike boom might finally be cooling off a bit. And what\u2019s Dave Rome\u2019s favorite chain checker? What\u2019s on the Nerds\u2019 wish list for internal cable routing? How do you graphics off of DT Swiss hubs? And do Cushcore gravel inserts work with all rims?\nWe tackle all of that in this week\u2019s Ask a Mechanic segment.
