Those are too completely different bikes (aero vs endurance), so your riding style/flexibility will be the deciding factor...if you are an aggressive rider and can handle the long/low position (and stiff ride), then go for the Orca Aero. If you are more of a laid back rider that values comfort, go for the Gan.


Personally, I'd forget about the Gan, and go for either the Orca Aero, or the standard Orca (team edition)...I own a 2018 Orca M20i Team, and absolutely love it.

Jenson USA has some deals on Orbea right now, so you could probably find a disc version with Ultegra for close to the price of the Gan.
