lots of pictures on this forum of people enjoying themselves on their MTB's
but why are they nearly always a bit tubby? lots of baggy freeride jerseys failing to hide a bit of middle age spread, and cheeky smiley faces with double chins.
obviously there are the racing snakes out there but they seem few and far between.
myself i'm skinny and most of the people i cycle with are of 'normal build'.
maybe the STW demographic is just more overweight than the norm?
or is a bike a lifestyle accessory that modern hectic lives only permit tubbies to indulge in a bit of cycling for a couple of hours a week?
