Cube Reaction GTC Eagle 29 Hardtail Bike

If you're looking for the ultimate in lightweight, race-bred hardtails, your search is over. The Reaction Eagle takes Cube's acclaimed carbon chassis and pairs it with SRAM's ground breaking X01 Eagle 1x12 transmission. Super-fast, clean shifts controlled from a single shifter leave you to concentrate on getting the power down to the trail. The result: Unmatched speed and control.

The 29" wheels allow you to carry high speed over a great variety of terrain.


Cube's engineers threw everything they know about carbon frame technology at the Reaction Eagle's chassis. That's why it's built with their stiffness-enhancing, weight-reducing Twin Mould technology and incorporates internal cable routing for cleaner looks and longer cable life.


No two ways about it - SRAM's X01 Eagle transmission sets new standards for mountain bike shifting performance.

With a single 34 tooth chainring up front and wide-ranging, closely spaced 12-speed 10-50-tooth cassette at the rear, the phenomenal gear range is on tap without frustrating, time consuming double shifts.

RockShox's reliable Reba RL fork and SRAM Level hydraulic discs with a 180mm rotor at the front round out the main components.

And Cube backed up all this phenomenal performance with a Fulcrum Red 44 wheelset shod with Schwalbe's light, grippy and fast accelerating Racing Ralph and Rocket Ron tyres.
