Tri Bike Shifting Component Question
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?

I picked up a Quintana Roo Seduza Tri bike last year. The bar end shifters are current Shimano Ultegra indexing shifters, same as any Compact group.

My road bike is a Specialized Roubaix triple which is very smooth and a comfortable ride. The Quintana Roo Seduza is a VERY DIFFERENT bike!! Much twitchier ride, less dampening and as any Tri bike, a more up rite seat tube. At first I though I had made a mistake in purchasing it, but, after a few weeks on the bike it started to become much easier ride. I originally had a fitting at the bike shop that gave me a very aggressive aero position. After riding it a bit, I performed some minor tweaks to give me a slightly more comfortable position. This took some time and was done over a few months.

Now, I like it as much as my Specialized Roubaix if the route isn't to hilly. My normal riding loop is usually 2-3 MPH faster on the Quintara Roo and I can comfortably sit in the aero position for an extended period of time.

Triathlon bikes are a different breed and take a while to get used to

Me personally I like the bar end shifters which still require some trimming. The first few times I rode with aero-bars it did feel a little akward with the weight being more forward. I have never owned a standard road bike and now I don't notice a problem at all. So you get used to the weight distribution quickly. If your back and shoulders were hurting it could be either a small pain until you get used to it or the set up could be completely wrong. I would highly suggest a proper fitting in the aero postion to get correct distances which should alleviate pain. If you buy a new bicycle ask if you get a fitting with the purchase. Some places will do that.

First off as far as I know the shifters look like the old "grind em till you find em" shifters. but they do actually have specific positions for each gear and if tuned properly work really well.

Second your pains are most definitely caused by improper fit and/or low flexibility. Even with low flexibility you can usually get a good fit depending on the geometry of the bike and if the fork hasn't been cut yet. If the fork hasn't been cut you can put spacers underneath the neck to raise the handlebars up. By raising the handle bars it will put you in a more up right position. Less Aero and less aggressive but more comfortable. It will still be more aerodynamic than other bikes just because of the body position. There is a lot you can do with fitting your bike and it would be highly recommended to be professionally fit. Find a reputable fit expert and get fit. Learn about fittings and use your knowledge to slowly move the positions around if you need to find something different. A good fitter will teach you about the positions while fitting you and why each thing they are doing is helping to improve your fit. Hope this helps and the best thing you can do is educate yourself as much as possible before making a decision.
