Ah. What I'm getting at is that if the bike is so new, I'm skeptical that it actually has 27" wheels -- I couldn't find much online about it, so I would presume it either has 700C wheels or 650C if it's tri/small-person-specific. Can you post a picture of one of the tire labels?
Cheap-and-great Panaracer Paselas are my choice. For everything.
