Our Performance Series Jogging Strollers feature the only one-piece frame in the industry, which means there are no hinges or joints to weaken during frequent, high intensity use. Their 20" wheels make it one of the easiest joggers to push on the market today - allowing you to run further with less effort. The sleek aerodynamic design and shock absorption system make it easy to maneuver whether going over rocky terrain or for a jog on the beach.
