Some countries/regions still have their idiosyncratic wheel preferences. For the most part, 26” (559mm) is still the wheel size of choice for touring in remote places around the world. 27” (630mm) may be abundant in Cambodia and other parts of Southeast Asia, but rarer than hens’ teeth anywhere else these days.

I think the pendulum is quickly shifting to 29ers (622mm wheel size or AKA 700c). As I mentioned in my previous post, it is now safe to tour in any developed nation with that size wheel. I would venture to say that by 2030-2035, it will no longer be a problem virtually anywhere in the world.

Then around 2040 when 26” wheels (559mm) are a long distant memory, the bike industry will start to rave about the great benefits of 26” wheels (559mm) - maybe with some little twist in new tech to them - and they will become popular again. LOL!!
