Generally speaking, this would be a simple recommendation for me. Most Cannondales have a persuasive piece of writing across the chainstays reading "Handmade in the USA," and that’s usually enough for me to decide. But the truth is, I have no experience with full-carbon frames. This is complicated by the fact that the shop mechanics are recommending the Tarmac over the Synapse for racing purposes.
I should clarify that he’s buying the bike for long distances–LOTOJA–so comfort is a priority. He also wants it to be "the last bike [he] ever buy[s]," meaning he doesn’t want to replace the frame in five years or something. He’s a bit of a climber, so weight could be in that mix as well …
I’d love to give the guy some advice, but the truth is that it’s a little out of my experience, price range, or league.
So let me know what you think.
