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.
