    Can anyone tell me if there is any type of regular maint. that needs to be done on dura ace shifters? Like greasing or the likes?

    The Shimano instructions have a Maintenance section, but that has only limited disassembly: how to take off the levers. Further disassembly isn't shown or recommended. No routine maintenance or lube is mentioned that I can find.

    I've heard of spraying lube into them if they ever stick, but nothing else. I don't plan to touch my new STI shifters...for what these cost, they should work for a long time without problems.

    Yeah, they come full of grease,cannot really be gotten into, and if they finally get crudded up, one possible fix is to hose them out with a suitable solvent and relube with something like triflo spray. A classic case of .... if it ain't broke, don't work on it till it is.

    Mine is broke, so... I have a Dura Ace STI lever that is misbehaving and I'm considering the disassembly route. Symptom: right lever will usually not shift from larger to smaller cog using the small inner lever unless I hold the larger outer lever still. Shifting from smaller to larger cog works fine. The outer and inner levers seem to move together when I try to shift larger to smaller using the inner lever and nothing happens. I have tried cleaning thoroughly with a spray degreaser followed by lube with tri-flow spray. It didn't make a difference. Any thoughts?

    Check to see if there is a screw still holding the downshift sti in place, it is a flipping small star shaped one, this is usually the cause.if not send off to service agent to fix, they usually replace under warrenty.
