Plus, it's possible to install knobby tires should you want to ride most of the time on dirt roads. 29er bikes have a knobby, mountain-style tire but in a 29-inch size. Hybrid and city bikes usually (but not always) use the Road bike's 700c tire standard. These are lighter to roll more easily on pavement for easy acceleration and climbing. There are 700c tires in different widths and treads for riding on all surfaces.
A beef roast cooked to medium-rare should have an internal temperature of 145Â°F - 150ÂºF after the resting period, and a roast cooked to medium should have an internal temperature of 150Â°F to 160ÂºF. (See the note below). See Beef Doneness for more information on proper cooking temperatures.
Ground beef must be cooked until the internal temperature reaches a minimum of 160Â°F to ensure that dangerous bacteria are destroyed. Ground beef dishes, such as meatloaf, should be checked for doneness with a meat thermometer.raditional guidelines for doneness state that beef cooked very rare, rare, or medium-rare should have an internal temperature ranging between 115ÂºF to 140Â°F. Many people prefer beef cooked rare (especially steak), but this decision is up to the consumer and is certainly not recommended by the USDA.
