So I finally got around to trying out my Red Handles... I got one left and one right (and they seem a bit expensive really at $250 each) and according to the Red Store the handle "Mounts on 19mm RODS or RED HANDLE MOUNT."
it seems the design is such that the small bolt supplied with the handle CANNOT actually tighten up against the rods.
Now I may be being stupid but somehow I don't think I am. Before the bolt can tighten the collar against the rods it hits a part of the collar and there is no way to go any further. The bolt can only be effective if it is inserted from one side (the thin side with the bigger hole) of the collar but it seems this is impossible to tighten. Someone tell me I am wrong please - it's a small detail but vital - it seems like a silly design oversight. Anyone from Red got a solution? Please?
