Hello

Does anyone know whether there is a 7 gear version of the shimano sis thumb shifter?
I attach I photo of the 6 gear one I have now used on two bikes and prevents me from upgrading. I am so used to riding with my palms resting on the shifters and like the ease of changing gears while wearing thick gloves I am reluctant to use any other type of shifters.
Also please note that I want the lever to be flat so that I can continue resting my palm on it. I am really looking for the exact same shifter but with 7 gears.

Thanks a lot
Tom
