Cube Reaction Pro 29 Hardtail Bike

This Reaction is Cube’s most popular all-round party machine. It features an Aluminium Lite frame construction and is equipped with mounts for a luggage carrier and fenders. Aside from being the ultimate weekend warrior with its superb component spec, this versatile ride is also the perfect option for weekday commuting and blasting around the city as you run errands in style.

Shimano 1×12 Drivetrain and Hydraulic Disc Brakes

A Shimano SLX/XT 1×12 drivetrain brings slick and smooth gear shifting and reliable performance throughout its entire gear range. Soaring you up the steepest hills on or off-road and getting you up to speed with the ultimate efficiency, this drivetrain’s immense speed capabilities are held in check by Shimano MT400 disc brakes when you need to scrub some speed.

RockShox Recon Suspension Forks and Cube/Shimano Wheels

Upfront this dynamic hardtail floats aboard RockShox Recon air suspension forks that glide you over knocks and bumps everywhere from off-piste trail hazards to inner-city cobbles. Rolling fast on Cube rims, Shimano hubs and Schwalbe tyres, this combination spins true and with virtually no flex for added confidence and stability no matter where you ride.

High-Quality Cube Finishing Kit for Comfort and Style

This Cube Reaction Pro 29 Hardtail Bike’s build is completed with a Cube finishing kit for the utmost reliability, comfort and style for all of life’s endeavours when riding on or off the beaten track.

Easy Assembly

When you order a bike, one of our trained mechanics will carefully prepare and pack your bike for shipping. Upon delivery, the assembly is simple and all necessary tools are conveniently included in the box.

Depending on the delivery service and destination, bikes will either be delivered in a large or a small box. Below is a guide as to how your bike will arrive:

  • All bikes for delivery within the UK and Republic of Ireland will be delivered in a large box, except for kids’ bikes and BMX bikes, which are always delivered in manufacturer’s boxes.
  • All bikes for delivery within the EU on a standard service will be delivered in a large box. If an express delivery option is chosen, your bike will be packed into a small box. Again, the exception is kids’ bikes and BMX bikes, which are always delivered in manufacturer’s boxes.
