Most of our testing of the Bridgestone X40F was performed in off-road zones where there’s about as much traction as an oil slick on polished concrete. So, with moist dirt being a pipe dream, having the correct front tire to handle the hardpack, rocky and sketchy terra firma is important.

The radius of the carcass is quite impressive, allowing for a large contact patch, and the tread pattern is aggressive for strong traction under braking. more >>
