Rocket S2
prime
Downhill
Rocket S2 is a carbon downhill mountain bike (2024), from Prime, in the Rocket series. It is a strong match for riders looking for a balanced off-road setup, with a setup that gives you a balanced riding position, while being more at home in gravity-focused bike park riding. Its profile is strongest in areas like capable suspension support for rougher terrain and a comfort-leaning ride feel over longer rides. That said, what it gives up slightly is less emphasis on outright speed than speed-focused builds and more of a flat-to-rolling terrain bias than a climbing focus.
