I've owned my current bike, KHS aluminum frame with Shimano 600 for almost 7 years. Recently I checked and cleaned every component except the bottom bracket and the sti shifters. I just did not want to deal with checking the bottom bracket as everything still felt fine. But my shifters are becoming very sticky and half the time are no longer shifting, at first I thought it could've been my cables stretching. After replacing my cables I am still getting times when i won't get a shift. When i move the levers it just sounds like the inside is completely gunked up. I tried googling on how to clean shifters, and searching here. Forum searching never really gets me what I need. I prefer working on bikes myself and I am able to do nearly all maintenance with ease, but I don't want to accidentally find out I destroyed my shifters as I don't have the money to spare for a new pair but how I would like some.
So I was wondering if anyone could explain how I would go about cleaning stishifters, or post a link. I will continue my search in the mean time and post if I find out.
Thanks in Advance.
