Hello,
I am just getting back into my cycling and trying to tune up my bike. I will try to explain the
problem I am having but I might not be using the proper terminology. I hope I can make myself clear.
I am setting up the rear derailer but I can't get it to shift correctly. When I start in the
smallest gear and shift it up to the larger gears (making it easier to pedal) it shifts just fine.
When I shift back down it always delays one shift except on the very last shift, then it skips one
of the gears.
Here is a more detailed description of the action. It is a 7 gear sprocket. When it is on the
largest gear and I give the rapid shifter one click the derailer only moves slightly and the gear
doesn't change. One the next click it does change by one gear. Now it will will change one gear with
each click until I get to the 5 gear where a single click will cause it to skip the 6th gear and
jump right to the 7th gear which is where it is suppose to be.
If at any time I try to shift back up to a larger gear, after I have been shifting down, the first
click will do nothing and then subsequent clicks will work properly.
I hope this is clear. Now my question is "What needs to be done to fix this problem." To me it seem
the spring in the derailer isn't strong enough to bring the chain back down again until the very
last gear. I am hoping there is something else which I can adjust. I tightened the tension on the
cable which helped the shifting to a larger gear. If I loosen the cable tension it will miss the
first shift going up.
Well, that's enough. I hope someone can offer some help.
Thanks.
Dan
