Gar29, I hadn’t thought about the possibility of riders dropping out after 60, but it seems more likely that there just aren’t that many who got into the sport back in the 1980s or 1990s who would now be riding in their 60s. If you’re seeing of lots of those in their 40s and 50s now, I guess we’ll know in another decade or so if most keep it up.
47 myself and riding with people between 20 and 60. 60+ MTB-riders, I met only randomly, most of them prefer road bikes. It’s not that they drop out at this age, most of them riding road bikes ever since. For myself, I can’t imagne to ride anything other than a MTB….
