Can I use an 8 speed shifter with a 7 speed cassette?
I have to replace the shifters on an older mountain bike.
The cassette is seven speed. I can get aShimano Ef28 Shifter with optical display that is for an eight speed cassette.
Will this work, but just have the eigth position on the shifter not workable?
I would use this with a Shimano Acer X derailure.
