It's right for you if...

You measure the success of a ride in the number of beautiful views, and when you're not riding, you're likely to be found planning your next escape. You hear the call of the open road and want a stable touring bike that's just as capable of carrying a heavy load on multi-day trips as it is on everyday rides.

The tech you get

A road-smoothing chromoly steel frame, alloy disc touring fork with a ThruSkew captured quick release skewer, wide-range 27-speed drive train that's great for hauling a heavy load up hills, Shimano Sora brake/shift levers, Bontrager Tubeless Ready wheels, puncture-resistant tyres with reflective sidewalls, included front and rear racks, and all-weather mechanical disc brakes.

The final word

520 is a comfortable steel workhorse that's capable of everything from daily rides to expedition tours. It's ready for adventure straight out of the box, with an included front and rear rack and a drive train that's ideal for hauling a heavy load.
