Last September Nukeproof presented the Reactor, the British brand’s new trail bike, available in both 27.5″ and 29″ versions, both offered in carbon and aluminum. During the Mountain Bike Connection Winter in Massa Marittima, Nukeproof showed us a new limited edition version of the Reactor, inspired by the bike that allowed Sam Hill to compete in some Australian cross country races for training.
The Reactor ST (Short Travel) is available exclusively with carbon frame and in three sizes (M / L / XL). It tips the scale at 12.7kg.
The geometry is adjustable in two positions and the rear travel is 125mm. The rear shock absorber is a FOX Float DPS Factory EVOL.
The FOX 34 Factory FiT4 fork has 130mm of travel.
The Reactor ST is available only in the version with 29-inch wheels, specifically with the DT Swiss XM1501.
The tires are cross country oriented – Maxxis Rekon Race 2.35″ with EXO casing.
The drivetrain is 12 speed Shimano with mixed components. The crankset is from the XT group.
While the derailleur comes from the XTR group.
The brakes are also Shimano, 2-piston XT 8100, with Ice Tech discs.
The cockpit is Nukeproof brand, with Horizon Carbon handlebar and a Horizon stem.
The cable routing is inside the frame and the chainstay and the down tube are protected by rubber fittings.
To complete the light trail setup that winks at aggressive cross country we find a 125mm RockShox Reverb Stealth seatpost.
