Just gathering more info for my D7 Sram Dualdrive ll build. The specs from the ebay auction say the Dauldrive has a 45mm chainline. I tried to measure my D7, and it looked like it could be 45mm, but I'm not 100% sure. Has anyone measured the chainline of the D7 and TR? I'm just wondering if I'm going to need to change my cranks and bb. Also, it looks like the spoke count on the D7 and TR is 28 on the rear wheel; my Dualdrive has a spoke hole count of 32, might this be undesirable on a 406 rim?
