    What are you gonna hit it on?

    Unless you frequently hit your front derailleur area (never heard of such a thing) it's not a problem. The seat tube mount is primarily aimed at frames that cannot take the BB mount version (frames with press-in BB's, etc.).

    OP, the seatube mount definitely will work. The BB model may or may not depending on the particular BB. External bearing BB's usually have a spacer between the shell and driveside BB cup that the BB mount model takes the place of. Cartridge style BB's (like Octalink) don't usually have spacers nor a "lip" to provide a mounting point. E-type compatible BB's do. As for chainring bolts, all 1x models come with spacers that'll allow you to use your existing bolts.

    Those guides work great if your bottom bracket can handle a spacer behind the drive side cup. One wit a lower bashguard can move, but those top only guides don't take the hits (or shouldn't unless you're very skilled at unique crashes). Octalink BBs aren't designed that way that I know of, so the extra thickness of the guide plate might prevent the non-drive side cup from properly bottoming out against the BB cartridge.
