Smooth rotation with ball bearings. It is more rigid than a resin pulley and does not release power. Ideal for upgrading bush type derailleurs installed on up to middle grade derailleurs. Can be used for both guide pulley (upper side) and tension pulley (lower side). For the number of teeth, we recommend the size that comes standard with the derailleur. 1 piece
