🔧 2. Bottom Bracket & Frame Compatibility Guide

Bottom Bracket Type Rotor Compatible Spindles Notes
BSA (Threaded) 24 mm / 30 mm Use BSA30 or BSA24 adaptors
BB30 30 mm Rotor cranks fit directly
PF30 30 mm Needs PF4630 or similar BB
BB86 / BB92 24 mm / 30 mm Rotor makes BB86/92-30 for wide spindle cranks
T47 30 mm Use T4730 or similar
SRAM DUB Not directly compatible Needs special spacers; better to use 30 mm crank or dedicated DUB
