Personally neither roadies or the MTB bother me but they do make me chuckle. Some of the roadies do think they're hot stuff though. Which on the last big bike ride was amusing since they'd always pass me but I'd also always meet them at the next rest stop. They spend 2x the time at each rest stop even though they were faster LOL. On the other hand the first bike ride I did also had a gravel route.. the MTB's thought they were tougher and better.. a few told me I should I try it. I had to tell them I grew up on a gravel country road you can keep it! I did alot of miles on $20 Huffy and gravel roads as a kid. For the most part it's light hearted ribbing as you two demonstrated. At least it's not as bad as Harley riders...
