Blaine "The Bison" Simpson helps Mountain Bike Action
test gravity products from time to time and he takes his testing seriously. So seriously, that he pushes it to the limit and sometimes over the limit. During a practice run at Southridge Racing's event today in Fontana, the Bison shows just how tough he can be on products and how tough he is (laughing to off).
The Bison is one very dedicated tester.
