The Baby Jogger Summit X3 has quality suspension on the front and rear wheels (supplimented by pneumatic tyres) for a smoother ride.
Front Wheel Suspension
The front fork wheel mounting system incorporates an effective but robust suspension system. It is the leading (front) wheel which causes the most abrupt jarring for the occupant upon impact with an obstacle (object, hollow or bump). Absorbing that impact improves the ride quality and reduces deflection of the pushchair from it's course.
Rear Wheel Suspension
The Summit rear wheels have a robust suspension system. Based on a 'sprung hinge' design the suspension permits movement up/down, forwards/back as is required to absorb jolts/bumps whilst preventing sideways movement - the lateral sway found with some rear suspension systems. The large 16" rear wheels offer a shallow angle of attack to bumps or hollows, combined with the rear suspension these enable a smooth ride to be enjoyed by the child.
