Can I use my Tiagra triple STI for a double?
I am replacing my triple chainset with a double. My STIs are Tiagra triple compatible. Can I use these for a double set up? Is there anything to look out for in set up so that I do not break the STI (on another bike I had supposedly triple / double compatible 105 STIs and the LH lever broke as I used it in a double set up). Thanks
