Some differences but mostly the same. The current pro versions have the aerodrive tri fork, handlebars, and stem integrated into an airfoil (plus tubeless tires, ski bend bars, and 11x30 cassette), but the non-pro 2016 has a traditional stem, alloy handlebars and fork (plus clinchers and 12x25). I've also heard/read that the Pro frames are stiffer with a different carbon weave but, even if true, would it be appreciably different @ my level of (in)experience? Are those combined differences minor, so-so, or significant?

If they're so-so+, I don't mind paying the extra $$$ to get a 2018/9 Pro 2 frame and upgrading components (can't find a new 2018 Pro 1 Large). But if those combined differences won't manifest in improved comfort and/or performance for me, then no need. Keep in mind I'm quite distant from the podium in my AG. My 70.3 was 3:30 for cycling. I'm assuming any of them will feel better than riding my aluminum clunker... but I'd like to get something I'll be happy to use for 3+ years.


Great, I wasn't sure what market there is for a new, Shimano 105 groupset. Was thinking of putting it on my road bike but I'd rather just re-sell it.
