Derailleur gears chain slack. Cage length determines the total capacity of the derailleur, that is the size difference between the largest and smallest chainrings, and the size difference between the largest and smallest sprockets on the cogset added together. A larger sum requires a longer cage length. Typical cross country mountain bikes with three front chainrings will use a long cage rear derailleur. A road bike with only two front chainrings and close ratio sprockets can operate with either a short or long cage derailleur, but will work better with a short cage. Manufacturer stated derailleur capacities are as follows: Shimano long
Word RAM RAM model, and was the original motivation for the model. Dan Willard used y-fast tries to solve this in formula_6 time. Michael Fredman and Willard also solved the problem using fusion trees in formula_7 time. Word RAM In theoretical computer science, the word RAM (word random access machine) model is a model of computation that is a random access machine able to do bitwise operations on a single word of bits. The model was created by Michael Fredman and Dan Willard in 1990 to simulate programming languages like C. The word RAM model is an abstract machine similar to a
