Hang on, what’s the issue here? Is it fair play because he’s a fat guy or fair play because he’s on a fat bike? If it’s fair play because he’s fat well whatever, he’s not that fat and he’s riding his bike. If it’s fair play because he’s on a fat bike, well that I do not get.
We’ve learned by this stage that fat and 27.5+ bikes roll well because rolling resistance is nothing to do with weight rather it’s to do with compounds and since it’s got the same rolling diameter as a 29er it should smooth out the bumps well. Since 29ers climb better than any other wheel size he should have an advantage there too with similar rolling dia, to say nothing of the increased grip and stability provided by larger wheels/tyres.
Now if he was hobbling himself by riding a 26″ or even a 27.5″ bike at what appears to be an XC or CX support race then fair enough. But since he’s riding what’s obviously a technologically superior bike which will make riding easier….I don’t get it.
