Certainly made a difference when I moved to another slightly hill area (10% max). As the ads said at the time "you will amaze other cyclists as they see you gliding effortlessly up hill" That was true. 15 years ago when I retired I like to visit many of the traditional Pubs around 10 mile radius. So dropping in for a few jars was never a concern (for cyclists) - no breathalysers for me - not that I was ever intemperate btw. I would mostly come home dark nights on the pavement - way too dangerous on the roads. Those were the pre Covid days alas.
