Shimano Triple Shifter Problems
« on: August 17, 2012, 12:53:25 pm »
When I'm in my largest gear and shift to the middle gear, the cable doesn't stop at the middle gear and goes to the smallest gear.  Then, I have to shift back up to the middle gear.  Has anyone had this problem?

This could be a lot of things.  Better shifters have four positions for the front derailleur:  small, left of middle, right of middle, and big.  It is harder to set up and maintain cheaper derailleurs.

What kind of derailleur and shifter are you using?

Start by cleaning everything around the derailleur--get rid of all gunk and try fresh lubricant.  After that you could need new cables and houseing, and then a new shifter.  This is hard to diagnose, so you may have to swallow your pride, open your wallet, and go to a bike shop!

One of the reasons why bar end shifters are popular, is that the front derailleur is run non-indexed.   You can continuously retrim the derailleur to the best position.
