Eric Barone broke his own World Speed Mountain Bike Record at an unbelievable speed of 138.75 mph, which is way faster than the top speed on my Prius. The Frenchmen completed the feat using a custom carbon fiber bike and suit on the steepest snow mountain bike track in Var, France. Barone proved that speed is not only found in the youth, as he completed the record at the age of 54. Congratulations Eric!
