Bought 2 26″ frames in the last 7 months. Why…because all my kit is 26″ and 26″ forks are pretty cheap at the moment plus serviceable, as well as at least one frame that I bought with the bottom failing out of the market. Unless they stop making tyres…which they wont, I’m pretty content.
Perhaps those that need an extra 1.5 inch are compensating for something else? ;)
