This addition of MBW Radio speaks with Bicycles Incorporated's John Meyers and Sean Meredith about mountain bike drive trains. John and Sean bring their 30+ years of mountain bike experience to the MBW Radio studios to speak about the new philosophy of 2x10 gearing, whether or not 3x9's are dead and a whole host of drive train related information. All of this and more on this edition of The Mountain Bike Whisperer Radio Show.
