Which rear gear for STI 8's?
I've been asked to fix a weather beaten Korean bike with an 8 speed STI drivetrain. The owner is struggling with money so I'm trying to do it cheap. His derailleur was sucked into the spokes and trashed and I've replaced the bent hanger but I don't have any specific 8 speed gears in my stash.
Can I use a Deore M730 or any other similar generation Shimano RD as a replacement? TIA
