Sometimes the best decision is to choose the entire drivetrain from a single group. The Core 400 shares the frame, geometry, and fork with the Core 300, but consistently relies on the Shimano Deore group with 1x12 gears for the drivetrain. This makes the tuning predictable and maintenance easy, as all parts fit together and are readily available everywhere. The hydraulic two-piston brakes and Schwalbe Smart Sam tires are designed for uncomplicated everyday and touring suitability, while the Alexrims MD30 rims with a 30 mm internal width provide a stable fit for wider tires. It remains a bike where you only have to focus on riding.
