Giga 297 Carbon Frame
Nukeproof
Downhill
Giga 297 Carbon Frame is a carbon downhill mountain bike (2023), by Nukeproof, in the Giga series. It suits riders looking for a balanced off-road setup, with a setup that gives you a balanced riding position, with a surface profile that is more at home in gravity-focused bike park riding. Its strongest points in the MatchBikes metrics are strong value-for-money versus many similar bikes, capable suspension support for rougher terrain, and strong speed potential on smoother terrain. What it gives up slightly is a firmer ride feel than comfort-first options and more of a flat-to-rolling terrain bias than a climbing focus.
