The Rocky Mountain Instinct A10 offers great adjustability and ride quality but falls short in component quality for its price.
Wide range of geometry adjustments
Fun and intuitive on-trail demeanor
Under-powered brakes and fork
Heavy (size large weighed 36.2 lbs)

Impressive weight
Shock tune not to liking
Limited compression damping adjustment
Difficulty accessing latter stages of travel with higher spring rate
