Cube Reaction Pro 2025 Teal/Holo Cross Country Bike

Available with Cube in the sizes shown above. Expect delivery within 14 days of placing an order.

The Reaction’s sleek looks are thanks to its Smooth Welded head tube and seat tube junctions. It incorporates a threaded bottom bracket and internal cable routing for long-lasting service and simple maintenance. There’s even a flat disc mount that integrates seamlessly with our kickstand mount, and integrated mounting points for ACID mudguards and carrier.

Trail-ready geometry includes a lower top tube and tapered head tube for more confident handling, cables run internally for reduced maintenance, and there’s plenty of room to run wide, grippy and comfortable 2.25in tyres. And, as your skills increase, there’s scope to fit a dropper post upgrade.

The Reaction Pro is all about the perfect blend of function, reliability and performance. That’s why we began with the precision of Shimano’s XT 1×12 gears, because they offer an enormous range and an unparalleled reputation for accuracy.

We added Shimano hydraulic disc brakes for their reliable all-weather stopping performance to help keep you safe, whether you’re out in the hills or battling across town. And we finished with the RockShox Judy Silver air fork, because it combines easy adjustability and a remote lockout with trail-smoothing alacrity. It’s the complete package.
