Trek Dual Sport 4 Disc Hybrid Bike 2021
If you're after a bike to conquer all kinds of terrain, the Trek Dual Sport 4 Disc Hybrid Bike is right for the job. Optimised for impressive performance on and off-road, this premium hybrid is exceptionally capable and hungry for adventure. The light Alpha Gold aluminium frame boasts agility and ensures you're never weighed down or held back, as does the addition of the SR Suntour suspension fork featuring 63mm of tasty travel. Surfaces are smoothed for a truly smile-inducing ride, wherever you choose to explore. The remote lockout means hands needn't leave the handlebars should you wish to adjust your suspension, so rolling from one type of surface to another is a breeze.
The 1x11 Shimano Deore drivetrain boasts easy maintenance and reliable shifting, as well as ensuring a wide range of gears for undulating terrain, so you can keep spinning regardless of gradient. The Shimano hydraulic disc brakes provide rapid stopping power in all weather and internal cabling preserves the sleek silhouette of this bike as well as improving cable longevity. Puncture-resistant Bontrager tyres will keep you cruising flat-free for longer, so you can get on with your ride. The Dual Sport 4 2021 is a versatile, comfortable and durable machine that's simply fun to ride - on any terrain.
