Pick it up here for less! The Super Record 12-Speed cassette features thinner sprockets, tighter spaces and space-saving dimensions that are the same as those of the 11-Speed versions. The addition of the twelfth sprocket allows a linear upshift or downshift by a single tooth, up to the seventh gear, allowing users to find the perfect ratio for any situation. In addition, the closer sprockets ensure faster, quieter and more precise shifting thanks to the special tooth design and surface treatment which guarantees a longer life span. The six larger cogs are available in two single-piece steel triplets, to avoid energy loss. Matching-thickness spacers eliminating the possibility of error during installation. Same overall dimensions as the 11 Speed; there are no wheels to change or update.
