2020 GT Sensor: Everything you need to know

When buying a new mountain bike, it can be difficult to get the balance right between the lightweight efficiency you find with a cross country bike and the capability of an enduro bike. This is why a trail bike comes with some compromise. This is where the GT Sensor comes in, in this post you will learn all about the 2020 GT Sensor to help you decide whether it is the bike for you.

Who is it for?

The 2020 GT Sensor is a mountain bike for most trail riders. It is very capable and would suit anyone that likes to go on all day rides, ride flow trails in bike parks or even take on the odd race. This bike sits right in the middle of a cross country bike and an enduro bike. Therefore, expect a good allrounder, but don’t expect to be a mega lightweight XC machine or to be attacking big alpine descents at top speed.

Details

Lots of mountain bikes are sold on the back of their racing pedigree and success, which is one of the reasons enduro mountain bikes are so popular. This is obviously backed up by the security of the extra suspension travel you get when the trails get a bit more technical. But the GT Sensor offers lots of versatility in comparison to many cross country and enduro mountain bikes.

The 2020 GT Sensor has had some improvements over the 2019 version. It has grown 10mm of fork travel, taking it to 140mm. The brakes have been upgraded too, especially on the higher specced versions.

The rear shock gives you 130mm of travel and is mounted using the LTS system. This is GT’s version of the Horst linkage system. It has been designed to improve braking performance, grip and bump absorption with a progressive feel. This is the smart decision for a bike with a short amount of travel.

The GT Sensor has similar features to the Force and the Fury. It comes with the Groove Tube, which is a neat recess along the down tube for external cable routing. This makes life much easier when it comes to changing cables and maintenance. Maintenance is also made simpler with the use of a threaded bottom bracket.

GT have designed the Sensor without choosing complicated or fussy details, which you will come to appreciate when it comes to cleaning it, changing parts and generally looking after it.

The seat angle puts the rider in a comfortable riding position, especially for pedalling. The head angle isn’t particularly extreme, but it suits the bike and makes it more capable than you would expect. The GT Sensor will take you over more technical terrain that topic wouldn’t dream of on older trail bikes.

Ride Characteristics

The design of the GT Sensor gives it similar pedalling efficiency to what you would find on a cross country mountain bike. This is partly thanks to the lock out function you get on the shock. The lever has two positions, open for general trail riding and locked, to stop it bouncing when you are climbing.

However, if you leave the shock on its open position, you will notice that the shock still offers a good level of efficiency. This makes the GT Sensor a good choice for all day riding when you need “just enough bike” for the terrain you tend to ride. The suspension set up gives you plenty of grip on rocky climbs and gives you a great feel when riding over small bumps.

The GT Sensor is a short travel trail bike, therefore you won’t be able to attack technical terrain at speed like you would be able to on an enduro bike. However, this doesn’t mean that you can’t ride techy stuff on a GT Sensor. It will still smash through technical sections with grin inducing vigour.
