When changing down left to right from the largest sprocket to the smaller ones, (low to high I guess), the chain skips the first 3 or 4 sprockets and then shifts smoothly for the rest. It's a road bike. What's the best adjustment? I've just cleaned up the chain and rear mech also.
I have a similar problem to Stormy. I can only get the chain to use the top 3 sprockets of the 7 sprocket set. When I change gears on the handlebar, I get a certain amount of resistance, but when the chain gets to the 3rd sprocket and I try to change to the 4th, there is no resistance on the gear lever at all and of course the chain stays on the 3rd sprocket.
Would shortening the cable length fix the problem?
I read your post as follows: "top 3 sprockets" are the "smallest sprockets", right?
- check limit screws
- try pulling the cable by hand and see if derailleur moves further to the "large" sprockets
if the hints / how-tos in the linked pages (2 posts from the top) do not help, something may be broken.
