I ride fairly regularly and while on a recent camping/bike trip in the Sierras I did a couple of rides with my girlfriend where we encountered some typical racer type riders on current/new racing bikes. Racing bikes are an amazing example of what today's technology can produce for cycling. But, with few exceptions, most of these kinds of bikes are built for racing. I ride traditional chrome-moly steel lugged frame bikes some road, some touring. On this ride I took a Randonneur bike with fenders, a front rack and a handlebar bag. It's funny how riders on racing bikes respond, they are either very positive, or dismiss you and won't say anything.
Having ridden both mountain and road bikes I'm often reminded how different the vibe is on the trail on a mountain bike vs. riding on the road. Riders are generally more friendly off-road. I'm not quite sure why, but there generally seems to be a friendlier vibe with mountain bikers than road riders. Most road riders, always seem more serious. Like mountain bikers, many are ready to lend a hand if you're stopped or seem like you have a problem. "You ok? or "Have everything you need?" which is always cool, but otherwise many road cyclists seem less friendly I think because of the more competitive aspects of road cycling. The macho road racer thing. It's silly when you think about it. There are lots of riders out there and most of us are out there to have a good ride, train or get better at the kind of particular riding that we might do. Whenever I occasionally encounter road riders that seem arrogant, it bugs me, because it gives cyclists a bad name. Some club riders I've encountered can be this way, particularly when riding in large groups. Not all but enough to make me write this. When I encounter riders who are like this, I don't say anything and just keep riding.
Not everyone aspires to being Mark Cavendish, Levi Leipheimer, Lance or many of other of the great racers out there. Although I admire these racers, I'm am not one of these riders. With few exceptions, the bicycle industry seems to continue to perpetuate the myth that the only kind of cycling worth doing is racing and being like Lance Armstrong or other top riders, as showcased in manufacturer ads. This may contribute to the negative macho racer attitude factor seen on the road.
One of the best encounters I had last year while on the road, is when after a long ride, having overextended myself early in the season and ending up on Skyline boulevard completely bonked, a mountain biker just getting ready to ride getting out of his car, saw me stopped, said hello and after I mentioned my situation, generously offered me some water and energy bars. He said "hey, we're all cyclists and need to look after each other".
I was really surprised and thoroughly grateful when this happened. On rides, I now take extra energy bars and water to possibly pass the favor along to another rider in the future.
Cyclists who really love the sport, aren't trying to prove themselves by being rude or arrogant to other riders while on the road.
