Giga 290 Carbon Frame
Nukeproof
Downhill
Giga 290 Carbon Frame is a carbon downhill mountain bike (2023), by Nukeproof, from the Giga lineup. It is a strong match for riders who want a more active, performance-leaning off-road feel, with a sporty, active riding position, with a surface profile that is more at home in gravity-focused bike park riding. The main strengths in the metrics are strong value-for-money versus many similar bikes, capable suspension support for rougher terrain, and strong speed potential on smoother terrain. At the same time, compared with more specialized alternatives, the compromise is a firmer ride feel than comfort-first options and more of a flat-to-rolling terrain bias than a climbing focus. Add this bike to compare on MatchBikes.com and see how it stacks up against similar downhill models.
