Ye They are well worth the money. They are designed to be taken apart to clean, they have sealed ballbearings so don't break as easily and don't go everywhere when you take it apart and they stay really clean. They run smoother than any other freewheel, have more engagements than any other freewheel, Have 6 pawls instead of 4 so have stronger engagements and virtually never skip and they don't come un-done every 5 minutes like a ACS .
