with EXACTLY twice the cable pull, I may know a way to divise a simple converter box, to be put in the rear shifter housing where ever you want it, to run ESP shifters with for instance an affordable Shimano derailer, and still benefit from the 1:1 thing. It would even allow for on-the-fly spring tension adjustment. It could even reverse cable pull if it would have to, to work with slow-drop derailers.

But then, however nice the converter box would be, Suntour seems to alreayd have derailers where the positioning of the cable on the derailer can be chosen to be 1:1 or 1:2 anyway, under or over the clamping bolt. Too simple. If only Suntour would figure out how marketing works...

But why bother? SRAM makes nice affordable deraileurs too..

The nice converter box thing would add extra weight too.

Dude, my espresso is all over my keybord! Please don't make me laugh like that again!

SRAM's affordable derailers aren't light, the light ones are extrmely expensive, and none are really ideal for road cassettes.
Suntour is very innovative IMO, but always manage to make a good idea look extremely dorky. What's on today's bigshot fork brands feature list, Suntour was does doing last year already. They TRY to be cool, but really aren't. Just really good value, whatever you maange to buy from them.
