#!markdown Cool. I'm a new engineer and I've done some similar calc's myself after seeing that Giant PR. -I was getting pretty even energies at a given speed. The larger wheels rotate slower, this cancels out the increased MoI? -the advantages in moments of inertia in different wheel sizes goes away if you use heavier tires! I did some calculations about contact patch and angle of attack as well. I think angle of attack comes into play when people talk about how much more fun 26 is because you can "feel" the trail better. Wheel durability is something that I feel is not being addressed. For the casual rider concerned about fun and not STRAVA or race times, it might be nice to have a wheel that you don't have to true as often…
