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 sort Students do not need to have strong phonics skills in order to engage in sound sorts. This can be a beginning phonemic awareness activity because students need only to identify the sound in order to complete the sort. Letter knowledge is not required, and phonemic development can mature as students do acquire more print knowledge. Picture sorts are one component of word study and are used to help beginning readers develop Concept of Word, phonological awareness, and phonics. Picture sorts most often begin with focusing on initial sound (single consonant, digraphs, or blends). By using picture sorts teachers are able
