• Quick question: can I replace post-mount calipers with flat-mount? Thinking of buying a used set of hydraulic road shifters that are being offered with hoses and post-mount calipers attached, but my frameset needs flat mount.

  • You don't have to. Get some flat to post adaptors, cheap as chips and you'll be riding much sooner.

    Flat mount is a con, if it is THAT good, it'll already be on mountain bikes! ;)
