Merged content of STI shifter page; deleted slightly erroneous content referring to indexed gear operation as synonymous, since indexing predates rapid-fire. Suggest that content be salvaged for an indexed gear page.
ye olde indexed (and some friction, IIRC) thumb shifters were badge as STi, too. Might want to explain that away in here somewhere. I think that's still the badge carried by the TY22 line, though i'm not sure.
STI is also used to describe flat-bar shifters with the integrated trigger-shifters and brake levers. --

Technically, STI refers to any Shimano shifter merged with a brake lever into one unit. This applies to the integrated rapidfires, MTB dual controls, and road STI shifters. The "Total Integration" is a reference to this integrated brake lever. Rapidfire shifters without a brake lever are not considered to be STI. It is also worth pointing out that the term dual control was originally used for their road shifters and refers to the dual function of the brake lever as part of the shift mechanism. Therefore, current XTR and Dura-Ace shifters are both STI and dual control. It is only an ad hoc convention that STI is primarily used for the road shifters and dual control is used for the newer MTB shifters.
