Anyone know the ins and outs of attempting to rebuild Ultegra rear shift lever? Parts avail? If I have to replace, is Dura Ace or Modolo Morphos the best bet?

Warranty is 2 years and is the best way to repair. Make sure that the little screw in the back of the brake lever has not fallen out. Move the inner shift lever a little to see it. It would be best replaced by D/A.

If the pin has fallen out, as it just did on the bike that I'm in the process of tyring to sell, is it generally a warranty issue?

I've done it and it ain't easy - this is coming from a semi-clever mechanical engineer, a kid who loves puzzles, and a bike nut. It took me over eight hours of messing around to get it back together and it still doesn't work 100%. You'll be money ahead if you can warranty it, pay some wizzard to rebuild it, or just buy a new one. Word is that the Modolo is crap. My next levers will be DA. You can buy just the sub assembly if you look for the PN on the Urup section of www.shimano.com. The guy at Shimano responsible for the little screw falling out of the backside of the Ultegra lever should be taken out into a field and shot.

That would be several times, starting at the arch of the foot.

No! Don't even try; just buy a new one. To the guy who succeeded, or semi-succeeded after 8 hours is either the most patient man in the world or a total Chucklehead (no offence intended). I tried once, after about an hour and a half it went in the garbage(and I work full time as a bike mechanic).

Like I said - I *like* puzzles and can be extremely patient, but I am thinking of changing my name to Chuck. ;-)

When I said it took me over eight hours it wasn't all at once. I'd work on it for a bit then put it down and come back another day and try some more. I was frustrated enough that I could've easily tossed to stoopid thing after an hour and a half on any given day. Eventually I got it, but the part I'm not sure about is the little switch mechanism - my Flight Deck no longer indicates the gear for the RHS. Could be the wires or it could be that the little symetric plastic switch tab went in the wrong way. Other than that the lever functions fine.

Once you figure in the LBS labor rate it makes zero sense to rebuild it.

Also a somewhat mechanically inclined engineer and it took me forever to get that thing back together. My problem was a little detent that holds the very first spring broke off. I had to re-make the part with a dremel tool and a piece of steel I had lying around. It's a shame to spend $180 on these things and not be able to work on them. I got a neck ache and my fingers cramped up from trying to put it all back together. Shifts O.K. but all my new levers will be Campy.

When my mountain bike shifter broke, I called Shimano and asked them whether I would be able to repair it. They informed me that no humans were involved in the construction of these shifters. I would guess the same goes for the road shifters.
