Will 8 speed STI left shifter suffice for on 9 speed FD & all 9 Speed bike?
Here's my situation:
Sorry for the long ramble, I just want to be clear what I have.
I originally purchased a 9 speed shifter (right hand) to setup a cyclocross bike with a single chain ring.
I then decided I wanted to go with a 2 x 9 speed option for cyclocross. For this, I shifted over my 9 speed shifters from another bike which was running a compact setup.
In the last 2 months, my wife has decided she's getting sick of her "comfort bike" and would like to go a bit faster.
Thankfully, we are both the same size and she can ride my Jamis Ventura Sport as an entry level road bike. All components on the bike are 9 speed, including the right shifter that I originally got (see above).
I'm just wondering if I can use an 8 speed STI type shifter such as the:
Shimano ST-2200 8 Speed left shifter
so that she can have a front / left shifter to interact with her 9 speed Front derailleur? Thoughts?
Won't the high and low limits and amount of throw I give the 8 speed shifter determine the shifting? I assume I can probably use any left shifter that is STI 8 speed? Left shifters are pretty dumb in comparison to right one's eh???
