When you're exploring, having the right gear at your fingertips is important. That's why, for the Nuroad EX, we chose Shimano's gravel-specific GRX 1x12 gears – they're dependable and wide-ranging. A Newmen Performance Gravel 25 wheelset equipped with light, tough and grippy Schwalbe 45mm tyres – and Shimano GRX hydraulic disc brakes – keep you in full control, all of the time. There's a vibration-filtering, full carbon fork for ride-all-day comfort. And a full complement of rack mounts – both front and rear – makes it easy to set up your Nuroad EX for anything from the daily commute to longer tours.
