Lyndall lug-drive rotors feature a highly advanced three-piece design, consisting of three components:
1.Outer friction ring (wear surface)
2.Inner carrier center (aesthetic portion)
3.Helical retaining ring that securely fastens the friction ring to the carrier center in a way that prevents their floating rotor from becoming loose or noisy after the course of its service life.
FLT `08-13 front rotors will work on `14-21 FLT models w/ Spoke or Aftermarket Billet Wheels
`18-Up Softails can use a 5mm rear rotor but may require pedal adjustment
