What the AI looks for in Bike Hubs

Axle standard and spacing: Match the frame and fork exactly (for example QR 100/135, 12x142, Boost 15x110 and 12x148). Check whether the hub ships with end caps that convert between standards. The hub has to fit the dropouts and work with your axle or skewer.
Spoke hole count: The hub's hole count must equal the rim's drilling (common counts are 24, 28 and 32). Hub and rim have to match one for one, or you cannot build the wheel.
Freehub body: Choose HG, Micro Spline, XD/XDR or Campagnolo to match your cassette, and confirm the hub maker sells the other bodies as swaps. The freehub decides which drivetrains the hub can run.
Brake mount: Choose 6-bolt or Center Lock to match your rotors. Choose a non-disc hub only for rim brakes. Adapters exist for some crossovers, but a native match is cleaner and lighter.
Engagement and bearings: More engagement points per revolution give quicker pickup, which helps on technical MTB terrain. Sealed cartridge bearings need less adjustment than cup-and-cone, while cup-and-cone can be rebuilt. These two features account for most of the real difference in feel and upkeep between hubs.

Hubs that do not list their axle standard or spoke count.
Proprietary freehubs with no other bodies available.
Buying a hub to rebuild a wheel without checking that the old spokes and rim will fit, since flange geometry changes spoke length.

Yes, but a different flange diameter or spacing usually means new spokes. Have a wheel builder calculate the spoke lengths.
