Hey everyone,

I'm deciding between the Koga Colmaro Extreme and the Cannondale Topstone 2. The key difference is the wheel size: Koga has 27.5-inch wheels, and Cannondale has 28-inch (700c) wheels.

My main question is: how uncommon are 27.5-inch wheels in comparison to the more standardized 28-inch?

I want to add that i want to go bikepacking with one of these bikes so i will be needing to put some luggage on them.
