hello - i have Shimano 600 STI shifters on my road bike and the 8 speed one has busted. I am trying to avoid buying brand new Sora 8 speed shifters because the bike aint worth all that much.<br />Is it likely I will ever source a used one from somewhere, or is it likely I could buy a used set of 9 speed shifters and 9 speed cassette/groupset etc.<br />any other options ?<br />cheers for any info ???
