Trek FX Sport Carbon 4 Hybrid Bike 2022
A sporty and agile character ensures that Trek's FX Sport 4 Hybrid Mountain Bike is ready for either your daily commute or to conquer any fitness goal. This bike is ready for any hybrid adventure by combining the speed of a lightweight road bike with the stability and comfort that comes with flat handlebars.
The frame's carbon construction offers a responsive ride experience that is also fast and comfortable and features mounting options for accessories, including mudguards and lights, giving protection on wetter road surfaces and visibility during the day or in lower light. An integrated DuoTrap device can link to your smartphone, offering in-depth ride data.
The Shimano Deore groupset delivers a smooth transmission, while the hydraulic disc brakes give reliable stopping power in all weather conditions, especially when paired with the wider 40mm tyres. Bontrager's Paradigm wheels provide reliability on any ride delivering a stiff and durable performance, and with the addition of the grippy gravel-specific GR1 tyres, this makes for a perfect combination for a mixture of rides.
