Shimano Index System (SIS)
Back
Announcement: VeloBase.com will be moving to a new server at some point later this week. During the transition period I will be locking out add and update functionality so that no changes are lost. During that period, you may be redirected to the Login page if you attempt to make an update. I will update the Announcement here once the process is completed. Posted: 11/23/20 02:01 PM CST

Short Name:Shimano SISYear Introduced:1986
Speed Range:6sp - 10spIndexed Component:Shifter
General Information
After being introduced in the Dura-Ace line, Shimano's SIS shifting system was altered when it was introduced into the 600EX product. Like with the Campagnolo Syncro system, the original design had too short of a cable pull per shift. This new SIS ratio allowed for more tollerance of friction and dirt in the shifting system. However shimano decided not to change the Dura-Ace system until 1997 when 9sp was introduced. This created an incompatiblity between Dura-Ace and other SIS systems.

Component List
Generally in Indexed systems, either the shifting or the derailleur component contains the indexing logic. Here is a list of components currently on VeloBase.com which utilize the Shimano Index System (SIS) shifting mechanism.
