As big brother to the highly decorated Mega, Nukeproof released the Giga to be the ultimate super-enduro mountain bike. Huge travel numbers make for a bike that performs on descents as close as possible to the full on Downhill race bikes while still remaining pedal friendly for those demanding enduro stages. Huge 170mm rear travel based around Nukeproof's own horseshoe rear linkage found on the Dissent DH bike works in perfectly in tandem with bang up to date geometry figures (63.5° head angle, 72.5° seat tube angle on size L, 1290mm wheelbase) to deliver outstanding trail performance. The result is simply an absolute weapon of a mountain bike. The 290 uses fast rolling 29" size wheels for all out speed, if you want a touch of agility then take a look at the mixed wheel size Giga 297.
