Yes, the SACHS 3X7 hub had a sterling reputation especially from people who put a lot of miles on it because it was very rugged. When SRAM bought out SACHS, they redesigned the hub to become the SRAM Dual-Drive which while good was not nearly as long-lived as the SACHS S7. SRAM ceased making the Dual-Drive hub in 2015 and no longer has anything like it. I would have kept the original S7 hub on my Greenspeed GTO but for the fact that SRAM really sucks when it comes to getting spare parts for their products. About the only way to get one these days is to find a used wheel with the DD installed. Utah Trikes calls the Sturmey Archer hub a "dual-drive" but it is not nearly as robust as the original which was actually trade marked by SRAM.
