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.
If tough, dried-out roast beef haunts you in your dreams, you know the importance of not overcooking meat. The more beef cooks, the less succulent it becomes; quality declines most quickly past medium, or an internal temperature of 145 degrees Fahrenheit. That's the temperature recommended by the U.S. Department of Agriculture, but for juicy, rare roast beef, you can't cook it that much.
