An excellent choice for a taller rider wanting a carbon gravel bike for mixed-surface adventures, longer rides and light bikepacking.
The Scout 31X is an adventure-focused gravel bike with a hi-modulus carbon monocoque frame and full carbon fork. That lightweight carbon construction gives you a responsive platform for gravel riding, while the tapered head tube and thru-axle wheel interfaces help keep the front end precise when the surface gets loose or uneven.
Its 1 x Shimano GRX 11-speed drivetrain keeps shifting straightforward, with a 40T chainring matched to an 11-42T cassette for a useful spread of gears across climbs, rolling gravel and faster road sections. The Shimano GRX hydraulic disc brakes with 160mm rotors provide controlled stopping, while the 700c x 40c multi-terrain tyres give the bike a versatile contact patch for mixed surfaces.
For longer days, the slim seatstays and gel-wrapped flared drop handlebar help take the edge off rougher gravel and give you a broader position for off-road control. There is also space for bags, bottles and more, making the Scout 31X a strong fit for riders who want one carbon bike for weekend exploration, daily route extensions and loaded gravel trips. This XL is recommended for riders around 185-193cm tall.
