ARC 50
Kellys
Race
ARC 50 is an alloy race road bike (2022), by Kellys, in the Arc series. It is a strong match for riders who want a sporty road feel without a full race fit, leaning toward a sporty riding position, with a surface profile that is best matched to paved roads. On MatchBikes metrics, it scores well for an aero-leaning setup that still keeps some versatility and balanced, versatile speed for everyday riding. Relative to category specialists, the trade-off is a firmer ride feel than comfort-first options and more of a flat-to-rolling terrain bias than a climbing focus.
