Looking for advice related to my first triathlon bike choice. A little background, I just started at age 43, did my first Sprint in May and have an Olympic in August. Plan to do a 70.3 next year and not sure after that. I don't expect to ever be highly competitive, but who knows. I think I finished in the top 30% of men in my first Sprint, but it was local and relatively small I guess (around 500 people total). I think I was around 7 of 20 in my age group, but a big gap between my time and the top 3 times. I road on a 2012 Fuji Gran Fondo 3.0 that I bought off Craigslist and I think it might be a size too large for me (M/L). My main objective is to get/stay in shape and to improve as much as possible within my abilities and training time limits. I'd like to get a new tri bike, fitted properly, that will last a while and I'm really interested in the idea of electronic shifting, both for smooth shifting and multiple shifting locations. Unfortunately, I don't want to spend a fortune, relatively speaking. It looks like the 2015 Felt B2 will be the first reasonably priced electronic shifting model ($3699). Assuming this fits me, any reason not to buy this model given my background/objectives?
