None of those things really, though it helps. Odd one isn’t it. I ride with lots of people that race and work hard in the sport, but there’s something missing.
I’d put it like this. Find a known rider, someone with credentials. An old pro would be best, one that doesn’t suffer fools gladly. If you can ride with them, and I don’t mean to be able to keep up. If you can spend all day with them and just understand all the nuances, then you’re probably a roadie?
Oh and we dig out out MTB’s for winter, and even race them.
