I'm thinking of purchasing a tri bike and tried a Quintana Roo Seduza and a Cervelo P2 Ultegra. I wish I could say the experience was great, but not only did I feel like I wasn't in total control of these bikes, but my neck/back started to hurt after only two miles and I was discouraged to discover that the shifters at the end of the aerobars were the ancient grind-them-and-find-them, lever-type shifters. I have a very nice Motobecane mountain bike with high end components including Shimano S2X DynaSys shifters and I don't understand why a $2000+ tri bike can't have these easy-to-use shifters. I know electronic shifters are available on tri bikes, for uber dollars, but I thought the old lever-type shifters went out with Fred Flintstone. Thoughts on why the old lever-type shifters are still used on tri bikes?
