Overview
About this bike
Designed for the aggressive trail rider, and built around a new take on GT’s iconic LTS design, the Sensor is a 130mm, 29er trail bike for the rider that wants to ride fast and focus on the fun of it. The alloy frame is engineered around a metric trunnion mount shock design, which allows for a longer-stroke shock, improving tunability and performance of the frame’s suspension, which you can manipulate to your liking with GT’s inclusion of a flip chip. The Alloy Sport controls this suspension with a X-Fusion 02 Pro RL shock, which mates seamlessly with a 130mm RockShox Rekon fork to deliver tremendous capability in a built-for-speed 29er platform. That speed comes from a SRAM NX 1x11 drivetrain, and gets laid down by a pair of grippy WTB Ranger Comp tires. Tektro hydraulic disc brakes keep it on the fun side of fast, and All Terra components keeps it lightweight with rock solid control.
