Chaps,

I'm preparing my Dawes Audax Giro 600 bike for sale as I don't ride it and I've found that the STI sifters don't work any more. My LBS had a look and reckon I need new parts but can't supply them.

Basically the handles move as if to change gear and the derailleur moves as expected, however, as the handle moves back so does the derailleur. I guess there's some kind of ratchet that's not engaging to keep the derailleur in place.

Has anyone had one of these apart? - does anyone have any spares? It's a 21 gear bike, so 7 at the back and 3 at the front.

Cheers

SR.

I had my RH shifter go like this (Shimano 105) a while back, needed to get a new pair, not user maintainable.

yep I'''ve never tried but I do believe they're a part that if you take them to bits you'll never get them back together. Don't know if you can easilly still get 7 speed sti levers tho someone might point you in the right direction......
