I have a couple thoughts around shifters after putting up with them for many years
I have big hands with long fingers, and generally shifters are a 1 stop fit.
Why can't a manufacturer produce a shifter that you can adjust where the actual shifter levers sits. Hope this makes sense... Bascially you could unscrew the bottom of the shifter and move the 2 shifters levers back and forth to any position that suited you. I'm sure this wouldn't be too hard.
Also I use 2 way release shifters on my modern bike and tend to ride with my thumb sitting between the 2 shifting levers. I have the latest Deore shifters. Hope this makes sense as well. Imagine if you could rest your thumb in between the 2 shifter levers, you press your thumb down (forward) and the gears shift to the larger sproket on the back and the larger sproket on the front, you then flick your thumb back and the derailuers move the opposite way.
I hope this makes sense? Perhaps if Shimano and SRAM are reading this
more adjustability for people that are bigger and smaller then the average.
