got handed down an old Univega 10 speed and restoring for boredom reason, and really diggin it, gotta new chain, and a chain remover tool, buuuut I dunno where I should unlink the ol rusty one at? Thanks for reading.
Check the chain for a master link. Chances are that it doesn't have one. This is where you get to practice using the chain breaker. Use the old chain to determine where to cut the new chain.
