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.
Step 1. Preheat your oven to 325 degrees Fahrenheit for a pot roast from the round; 425 degrees for a pot roast from the chuck; and 350 degrees for a pot roast from the rib. The weight and type of roast determines the cooking time; you should cook a roast until its internal temperature is between 135 and 150 degrees F.For instance, a 2- to 3-lb. rump roast cooks for 1 Â½ to 2 hours to medium-rare doneness, the Cattlemen's Beef Board and National Cattlemen's Beef Association website advises.tep 4. Remove the pot roast from the oven when it is 5 to 10 degrees below the recommended final internal temperature. Cover the roasting pan loosely with a tent of aluminum foil and let the roast stand for 15 to 20 minutes. The internal temperature of the roast will rise another 5 to 10 degrees.
