Rocket FRAME

Downhill
Rocket FRAME is a carbon downhill mountain bike (2023), by Prime, in the Rocket series. It suits riders looking for a balanced off-road setup, leaning toward a balanced riding position, while being more at home in gravity-focused bike park riding. Standout strengths from the metrics include capable suspension support for rougher terrain, strong value-for-money versus many similar bikes, and balanced, versatile speed for everyday riding. 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. If this looks close to what you want, compare this bike on MatchBikes.com against similar models.
