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 Comp controls this suspension with a RockShox Deluxe R shock, which mates seamlessly with a 130mm RockShox Sektor fork to deliver tremendous capability in a built-for-speed 29er platform. That speed comes from a Shimano SLX drivetrain, driven by a Race Face crank and made possible by a pair of grippy Schwalbe Nobby Nic tires. Shimano hydraulic disc brakes keep it on the fun side of fast, and a dropper post ensures you’re wringing every last drop out of the Sensor, both on the way up AND down.
