OK new disc frame, setting up all going well except...ive come to do disc alignment + chain tension using snail cams. Basically I want the disc as far in the dropout as Possible to give maximum coverage of the brake pads on the disc surface, BUT my chain becomes floppy, but not enough to remove a link Im going to try a different chain for now, but if that doesn't work, is my only option a tensioner? thanks...any suggestions most welcome
