Andre Greipel, the Incredible Hulk on wheels.

Massive Attack.

Yes, he has a big leg up. Two to be exact.

Experts, director sportifs and other sprinters were astounded by the speed, strength and dominance of Andre Greipel in the 2010 Tour Down Under. Many theories were floated — EPO-laced sauerkraut, bionic limbs, selective gene splicing, a small turbo surgically inserted between his heart and legs.

But it was Saxo’s Banks Stuart O’Grady who had the correct answer. The Australian simply said look at the considerable bulk of his legs. The photo above was taken at the 2008 TDU and you can only imagine how massive those thighs appear now.

This man is the Amazing Hulk on wheels. When his skin starts turning green we’ll have full confirmation.
