Anyone ever have STI levers rebuilt? Who will do it? Is it cost effective? I had a mini screwdriver break off inside and jam up the mechanism (long long sob story).

... they're generally regarded as having "no user servicable parts inside"...

That said, depending on what's going on... you might find some useful info at

They offer a few exploded (PDF) views and parts lists on some of their STI shifters, for example...

In general, it's not cost effective... but there are always exceptions.

Decided to tackle it myself, since it's effectively toast anyway. Took it apart, springs came flying out. Got the offending shard out of the mechanism, and started to rebuild. Had to make a few educated guesses, but I'm one spring away from finishing. The problem is, it's a pretty big coil that needs to be preloaded quite a bit. I'm using a loop of fishing line to pull the spring in a circle, then trying to make it catch. Three hours later I need a drink and a hug.

I don't have a solution, but I admire the problem

I like the cut of your jib... that is, if you've got nothing to loose, then, why not!

Hopefully, you can take a break... get a bit of rest... tackle the problem fresh... and have a happy outcome!

... oh, and... hugs...., but in a MANLY way!

Be the bike.

If you have an inside line as to where to get the body (black plastic that all the guts screw to) let me know as I have a second hand shifter that appears to have been overtightened (and cracked). Otherwise, the springs etc. seem to be working fine, but with this cracked body, it will not hold to the bar.
