I have my bike setup with a DA 7700 9 speed double setup with aero bar/bar end shifters. Have been meaning to switch it to a regular setup with sti shifters- never thinking about the fact that I wouldnt be able to buy them new forever. Now I am stuck trying to find something in good shape off of eBay. I saw a new set- but it is a triple. I read that you can adjust it so it just uses the middle- upper settings. But will my local bike shop know how to do that? Just wondering if this is a viable option or a jerry-rig that will give me problems.
Would also be interested if anyone knows which Ultegra option might work. I tried looking at the charts and as a non-expert I found them to be very confusing. Thanks!
too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
Yes, this is a viable option, and your bike shop shouldn't have any problems setting it up for a double. It shouldn't be a challenge because many mid level Shimano road 9s STI levers only come as triple/double and the left is used as a double or triple according to which crank with no issues or special adjustments.
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
With 9-speed Dura Ace, components from any of the other 9-speed Shimano groups (105, Ultegra and Tiagra) can be used interchangably. If you set up a triple shifter to work with a double crank, tell your LBS to adjust it so the two "outer" clicks select the two chainrings. That way if you accidentally try to shift into a non-existant gear, you only get a slack cable, not a damaged shifter.
Another option would be Campy 11 speed. I have no personal experience with this but I understand it will shift Shimano 9 speed just fine. You could buy new Campy shifters for what you would pay for used Shimano 9 speed.
