Any suggestions? Thanks!
Say all the postings about WD40 and solvents and really don`t suggesy you try that on the bike. The prime ingredient in WD40 is actually a light mineral oil and all oils and solvents can swell rubber so your brake hoods and anything else in the area need to be removed so why not just take off the shifter?
Tech socuments and a parts list are probably available from Shimano but that doesn`t mean parts are available.I`ve been waiting 6 months for some 2010 parts that were ordered from Shimano so it might be simpler to look around and see if you can find something second-hand and replace the whole unit.
I guess if you want to tinker and are mechanically inclined you could take this one apart. That would be the ideal way to service it anyway. Some of the stuff that might be in there won`t get washed out with a rince anyway. Its ridulous how many spiders think these things are personal condominiums1
