The Rockcentric's is a top seller, its success can be attributed to the combination of: curved sides seating much more effectively than the flat sided nuts, the all-around ease of placement or removal and the light weight compared to the original Hex.
As people replaced these old Hexes on their racks, they noticed the other big plus point for the Rockcentric was it's versatility, in that one nut can provide four placement modes. And as of two of these were 'camming style placements', they made an effective starter tool for those who couldn't afford or weren't confident using cams. |
