If you’ve been following the trend in mountainbiking world, you would surely have heard the relentless, exhaustive mantra spelled by journos and brand spokepersons: “bigger is better”.

And why don’t automobile and motorcycle industry adopt the same philosophy? They were quick to point out the strengths of bigger wheels… is there something they didn’t tell us?
