I may be wrong about that, so correct me if I am. I figure that there is a tradeoff in there that all manufacturers have to contemplate - did Shimano and Sram pick the same distance?
(UMD, IIRC, you have wrist issues- did you ever try a Shimano front der?)
Yeah, but I thought they only used the zero-loss technology on the right shifter with the Rival/Force stuff, not the left. Did they apply it to the whole line?
Thanks again. - b.
The movement of the derailer and the arc of the shifter are independent. A certain amount of cable has to be pulled to make the derailer shift. But the shifter is indexed, and regardless of the amount of lever arc movement, both SRAM and Shimano both move the same amount of cable from one index position to the next, even though they don't have the same amount of lever arc. The "zero loss" was added for the front, not the rear.
I don't have any wrist issues, but what I do have is a circulation dissorder (Raynaud's) that causes me some difficulty in colder temps, such that I have trouble feeling the lever and my fingers would slip off of them over the long throw of the older Force levers, but with the shorter throw of the Red levers it is not an issue (and would be the same for the new Rival/Force).
