GT has overhauled the Sensor, creating what it calls the ‘most capable trail bike it’s ever designed’. There three main options to the new Sensor range; carbon and alloy-framed versions, and an ST with shorter travel for a more poppy, responsive ride.

Need to know:

• 29er wheels
• Available in 4 sizes: S, M, L, XL
• Carbon and alloy versions
• 140mm rear and 150mm front travel in carbon version
• 130mm (r) and 140mm (f) in alloy version
• Short travel ST version has 120mm rear travel and 140mm fork travel

‘Same name, new bike’ according to GT

The Sensor last got a refresh back in 2019, but this isn’t just a tweak. There’s almost a whole new bike bearing the Sensor name now, with up-to-date geometry, lighter weight and a selection of different build options. GT calls this a trail bike, and given the breadth of modern trail riding it’s hardly suprising that there are different specs to suit whatever definition of trail you like to ride.

On the carbon version of the bike, the new front triangle design and carbon seat stay, combined with component choice, saves an impressive 600g over the former version according to GT. There’s also tube-in-tube cable routing for a sleek appearence, easier maintenence and a quieter ride.

Geometry is longer and lower with sigificant increases to the reach and wheelbase, and a lower standover height. The Head tube angle has changed only slightly on the carbon version, from 65.5 degrees to 6.4 degrees. There’s more of a change to the seat tube, steepening up by 1.4 degrees from 76 degrees to 77.4 degrees.

There’s more travel too on the Sensor Carbon, with 140mm rear travel in the form of either air or coil shock, and 150mm fork travel.

GT Sensor ST Carbon

For riders who want something more playful, responsive and poppy on less chunky terrain, and are all about speed, the ST model – short travel – has 120mm rear travel and 140mm front.
