Original Rough Roller
All manual designs have a custom adjustable dual shock suspension for a cushioned ride for any weight. Even more importantly the suspension compensates on tricky landscapes. The suspension can help you power your way out of a hole, bound across rocks, logs or brush, negotiate a stream, river or make the transition from sand, snow or soft dirt back to hard surfaces. The suspension creates a "perpetual motion" effect, causing the chair to spring forward or back in a tricky situation.
