I recently got a bike with a 7speed cassette with down tube shifters. I have a pair of STI levers for 8 speed. Will they work together? I realize there would be an extra click but is the spacing the same for 7 and 8 speeds?
If they won't work, what are my options for putting indexed shifting on the handlebars for my 7 speed bike. I noticed bar ends only go to 8 speed.
