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.
Move the roast beef onto a serving tray to rest for 10 to 15 minutes. Its temperature rises another 5 to 10 degrees, putting it at 130 to 135 F for a perfectly pink medium-rare. Juices also get reabsorbed into the muscle fibers during resting, sparing you the unfortunate loss of flavor and moisture that results when unrested beef is cut.
