With 120mm of travel and 29-inch wheels, GT's Sensor 9R Comp has yet to meet a trail it can't handle. Its light, efficient GT Speed Metal aluminum frame boasts their Independent Drivetrain Suspension for outstanding bump compliance with super-efficient pedaling. Up front, there's a SR Suntour fork to help you pick your way confidently down the steepest, most technical drops as you roll right over anything on the 29er Alex wheels and Maxxis knobbies. Meanwhile, in the components department, you get a precision-shifting drivetrain FSA/Shimano drivetrain, powerful Shimano hydraulic-disc brakes and a fine stem, bar, seatpost and seat from GT.
