A friend of mine that has competed in ironman competitions saw one of my touring bikes one time and commented that he was unaware that you could put tri shifters on the ends of a handlebar like I had it set up. I asked what a tri shifter is, he pointed at my bar end shifters and said those are tri shifters. Different cycling backgrounds appear to have different lingo and if you buy a time trial bike for triathlons, I can see how they end up being called tri shifters by triathlon competitors.
