The Revolution PRO DUALLIE is the most deluxe, 2-kid all-terrain stroller from BOB, the #1 jogging stroller. Hand-activated rear drum brakes make for the best downhill control. The front wheel can swivel for top maneuverability or lock for added stability. The state-of-the-art adjustable suspension system takes bumps in stride and the adjustable handlebar provides a perfect fit for any parent. Pair it with the BOB B-Safe 35 Infant Car Seat by Britax to create the ideal travel system.
