In my experience yes, but with limitations.
I have a stick that I take travelling or to races as they are far more convenient than my roller (not helped by the fact my roller is actually a 3ft long pilates one).
Good for most musche groups except I can struggle to do the top of my ham strings and glutes as I can’t get enough force onto it. Rubber ball can be a lightweight substitute.
In general I’ve found sticks, rollers and balls to be far and away the best thing to help recover after racing and hard rides. Much more so than protein shakes and stretching. For that price I’d buy one and try it out.
