In Colorado, for roads that are not posted, speed limits are:
Speed limits should not be set higher or lower than these limits unless a traffic study has been performed to justify the change. This applies to all state highways, county roads and city streets. The study includes an analysis of roadway conditions and accident records and a count of the prevailing speed of traffic. A safe and reasonable limit is then established at or below the speed at which 85 percent of drivers travel.
See "Establishing Realistic Speed Limits" on the Colorado Department of Transportation website for more information.
