What the AI looks for in Mountain Bike Frames

Wheel size and fork travel: Match the frame's wheel size (29 in, 27.5 in, or mixed) and its designed fork travel or axle-to-crown length. The wrong fork changes geometry and can void the frame warranty.
Rear shock fitment: For full suspension, note eye-to-eye length and stroke, the mount type (standard or trunnion), and air or coil compatibility. A shock that doesn't match won't fit, or will run out of travel.
Rear axle and derailleur hanger: Boost 148x12 is the current mainstream standard, and Super Boost 157 is less common. A UDH hanger is needed for SRAM direct-mount Transmission. These decide which rear hubs and drivetrains fit.
Bottom bracket: Prefer a threaded BSA 73 mm shell over press-fit. Threaded BBs are easier to service and less prone to creaking.
Dropper post compatibility: Check the seat tube diameter (30.9, 31.6 or 34.9 mm), internal routing and maximum insertion depth. Insertion depth limits which dropper travel you can run.
Brake mount: Post mount, noting the native rotor size (commonly 160 or 180 mm). Native rotor size limits braking power without adapters.

Frames with obsolete standards (non-Boost spacing, straight head tubes, 26 in only) unless you already own matching parts.
Forks longer than the frame's rated travel.
Bargain frames from brands that have closed, because warranty and spare parts disappear.

Only if you want SRAM's direct-mount Transmission drivetrains. Otherwise it is a nice-to-have, because the replacement hanger is easy to find.
