Bought a used bike with Ultegra 9 speed STI. I have always used friction shifters so I'm not sure if this is normal or not. The Left shifter seems fine. When shifting down with the Right shifter it seems fine. But when shifting up with the Right shifter it goes over to left OK but often will not return unless I aid it by manually helping it back. Does it need lubrication to snap back on it's own?

Thanks in advance,

You can try lube (I assume that the cable needs no adjusting if it is shifting normally) but I'd be concerned that the shifter is trashed. Whooops, bummer.

As stated above. Nope, not normal. Might need some adjustment, might need a rebuild if you can find a shop to do it. I'm no full bore wrench. Otherwise, to replace, they're not too expensive if bought used. Heck, I've got a spare set if you're interested, Ultegra 9 speed. Or you can just deal with it as is.

On the underside of the right shifter, there is a small screw; look closely for that screw, it is a philips head and is easily accessable when the shifter is moved to the shift position (the left swing full shift and hold open) That little screw can loosen and hang up the works. Tightening that screw is really not the solution. Blue loctite and tighten the screw. If that is not the problem I would start to look at cables being frayed somewhere or the nut that is under the Ultegra cap.
try WD40...PeterRider

... maybe you have old dirt stuck in the lever. I found that WD40 is great with Ultegra STI shifters :)
