The GT Sensor Al Comp packs lightweight power and aggression as a dominant dual suspension mountain bike which knows no limits. This versatile mountain bike tears up any trail with speed and power while remaining agile enough to tackle technical terrain. GT's alloy frame is light and incredibly durable which will help you test your limits and perform at your best, setting the standard for the rest of the components on the Sensor.

The RockShox 35 Gold RL fork with 140mm travel and RockShox Deluxe Select+ RT Rear Shock for a formidable suspension rig which is incredibly capable. While the Tektro M745 Hydraulic Disc Brakes with 180mm rotors give you powerful braking control over the Sensor. You'll need this power since you'll be powering through the trails on the 1X12 speed SRAM SX Eagle drivetrain which offers sleek shifting and high-level performance. The 1x12 setup is simple to minimise maintenance and any mishaps on the trails, yet still offers the range of gears to get you where you need to go. The Sensor rolls with tubeless ready rims and Schwalbe Nobby Nic Peformance 2.35" tyres for an unbelievable ride. You'll be riding at the top of your game with the TranzX dropper post which gives you the ability to adjust on the go.

The GT Sensor Al Comp will have you carving up the trails, with no trail too challenging for this relentless dual suspension mountain bike from GT.
