CUBE NUROAD EX is a versatile gravel bike designed for fast rides, gravel adventures, daily commuting and longer touring. Combining road-bike efficiency with off-road capability, it features a lightweight Aluminium Superlite frame, full-carbon fork and a gravel-specific Shimano GRX 1x12 drivetrain.

The Shimano GRX 1x12 drivetrain combines a 40T chainring with a wide-range 10–51T cassette, providing a broad selection of gears for everything from steep gravel climbs to faster road sections. The Shimano GRX RD-RX822-SGS rear derailleur is designed specifically for demanding gravel riding.

For confident braking in changing conditions, the NUROAD EX uses Shimano GRX hydraulic disc brakes with 160 mm rotors front and rear.

A lightweight CUBE C:62® full-carbon fork helps filter road and trail vibrations for improved comfort on longer rides. The fork also features lowrider mounting points, while the frame provides mounting options for mudguards and a rear carrier, making the bike easy to adapt for commuting, touring or bikepacking.

The Newmen Performance X.R.25 Tubeless Ready wheelset is paired with wide Schwalbe G-One R 45 mm tyres, offering a balance of grip, comfort and efficient rolling across asphalt and gravel. The frame provides clearance for tyres up to 50 mm wide, or up to 45 mm when used with mudguards.

CUBE's Size Split concept uses 27.5" wheels for the XXS frame, while XS through XXL sizes use 28" wheels, helping provide suitable proportions and handling across the complete size range.
