Stripping Dura-Ace 9-Speed STI Levers

Dura-Ace levers are the most serviceable of all the 9-speed STI levers. They are readily dismantled and can be separated down to the most basic components. All the more pity then that spare parts are not available.

These pages are specific to Dura-Ace 9-speed STI levers. They show the strip-down and re-assembly of the ST-7700 family of levers, specifically, ST-7700-C left & right and ST-7703 triple levers. Earlier 7700 range levers are very similar and differ in only minor detail, mainly related to the Flightdeck interface.

9-speed Dura-Ace was introduced in 1997 and continued until superseded by 10-speed in 2004. The triple option was introduced in 2002.

The construction of levers is very similar and procedures and photographs have been combined here. Where there are important differences, these have been highlighted. Note that levers are handed and most parts are not interchangeable left to right.
