>>1872339>finding replacement components on the same level of quality as the originals is very hard.wtf are you talking about?
This is a frankenbike so i don't care but lets say it was a complete 9 speed ultegra bike, stock. There's absolutely nothing wrong with the readily available consumables for that.
You think a Sora or Alivio level cassette is gonna shift worse than vintage Ultegra? The difference is it'll be a little bit heavier and probably wear better. And the new higher-spec 9 speed chains are likely better than anything you'd get then. BB is the same.
