Three speed STI shifter on two speed crankset I just bought old Shimano RSX STI shifters for my 90s road bike, which had a Shimano 600 Tricolor Group (2x7) with downtube shifters.
While the rear shifter I bought is correctly a 7 speed one, the front one is a 3 speed one. Is there any way to adapt it so it works on the 2 speed crankset and derailleur?
Thanks!
Just set it up and adjust it as you would a two speed shifter. Make your initial adjustments using the first and second shift positions. The &quot;HIGH LIMIT&quot; screw on the front derailleur will prevent you from reaching the third shift point.
