Shifting Adjustment advice(5 posts)

I'm not that familiar with adjustments available to me on my Dura-Ace equipped bike. Here is the issue. I have about 1000 miles on this bike and have now noticed that the gear indicator(that little orange piece in the clear tube attached to the shifter cable) has experienced a "change" Originally, when I was in my largest(most teeth) cog on the rear this indicator would be all the way to the right. Now it appears to rest a little further left. This often leads me to believe I have a gear(or two) left on a fairly torturous climb, when in fact I don't. Are there any adjustments I can make to correct this or do I just recalibrate in my head?

I don't know but it sounds like a cable stretch problem. Have you re-adjusted cable tension? This is a normal adjustment on a new bike (or old), your LBS should adjust cables, derailleurs, brakes, etc. on your first return visit.

If we're right, I'll bet your shifting isn't real great either. Ride your bike up and down the street. Shift into each gear and see if each shift equals exactly one gear change. If you think that your bike is shifting perfectly, try to live with the gear indicator the way it is. If not, you should get it fixed.

If you want to try adjusting it yourself (and I think you should) try this: Stand behind your bike. Look to where the shift cable attaches to your rear derailleur. Try turning the barrel adjuster that you find there 1/2 turn counter clockwise. Do the gear shift test again. If you think that it's worse, put it back the way it was and take the whole bike to your LBS.

If you think that it's better, continue to fiddle with the barrel adjuster until you get it perfect. Just remember how much you turned the barrel adjuster each time so that you can undo it if you think you made a mistake.

Good luck!

Sounds like the orange 'ball' just shifted. Shift all the way to the smallest cog and let the housing push the orange ball back into the proper position, then see if it'll go all the way to the right again. Whether or not your indexing is properly adjusted, the orange ball should travel the full range.

that little orange guy just floats in there with light friction holding it onto the cable. That's why you need to go through the whole range of rear gears every so often (if you don't do it in the course of a ride). There's really no other way to center it on a particular hatch mark in the clear tube indicator.
