So you're saying that the amount of cable pull for the hammerschmidt is the same amount as going from big ring to granny gear in a three ring setup? Right now I have a two ring setup in front and rotate the twist shifter about 1/4 to 1/3rd a turn to go from one gear to the other. Will I be twisting the shifter more or less with a HS?shag555 said:The way front derailleurs are set up the ratio must be somewhere around 3:1 for a shift. The grip shift rotates a ton in order to meet that. On the HS, all you need is about 3/8" - the same amount that the shifter would move a front derailleur from the big ring to granny gear, and that's the problem.
So it sounds like the HS needs more cable pull than a standard derailleur.... at least with your shifters. Wonder if the current x.0 twisters have more pull or not? If it's the same, then that's no good, you couldn't shift quickly as you'd have to rotate your hand quite a bit to get a front shift..... might have to just do a trigger on the left and twist on the right and call it a day.shag555 said:I might be wrong about the amount of travel (IE 2 ring vs 3 ring setup). However, in order for mine to activate the 1:1.6 overdrive, my gripshift needs to go from "granny" to "big ring" in order to fully lock in the HS. My gripshifts are circa 2000, so who knows what the ratio was (I'm just guessing).
It'll take off once there's not such a price delta between a standard setup.shag555 said:HS takes off and proves its self (like I think it will).
