Anyone who's into cycling knows that there is a huge difference between a cruising bike and a high performance bike. The same applies in the world of stroller-dom, yet until now there has not been a dedicated high performance jogger. sub 4's unique frame geometry allows for unparalleled stride length, one handed maneuverability and optimal posture for active parents. With state-of-the-art suspension technology absorbing shock, 20" rear wheels decreasing roll resistance, and a handbrake for complete control, sub 4 is dedicated to high performance running with kids. No compromises. The world's fastest jogger... The power and freedom to walk, run, or jog.
"The Sub 4 stroller is everything we want in a stroller as its simple, streamlined and light." - Deena Kastor, current US women's marathon record holder
