The first thing that crossed my mind was "hmm, they're gonna offend some Clydesdales and Athenas and make others laugh. They're pretty bold with this one". Luckily another cyclist on a Surly Long Haul Trucker rode in just as I was leaving and explained the slogan to me. Turns out Surly is referring to fat tires fitting between the chainstays, not the weight of the rider. Whew! I almost came on here and made a fool out of myself! I was all ready to let people know that Surly advertises C/A-friendly bikes.
