If there is one thing I find really annoying about Shimano, Sram, and that Campy fellow.... is that no one will make a great 7 (or even 8) speed
system so you can have a low Q. I have a terrific titanium bottom bracket ( about a 107 or 108) that the fixie guys would just drool over. It'd fit their bikes perfectly. And it would provide better pedalling than the newer and wider systems. And stronger wheels, and more longevity in gears and cranks, and a microspcopic increase in pedalling smoothness.
With all those advantages, you'd think somebody would make
a gear system that was better instead of more.
You could shim the rear to get the equivalent of 130mm, and use a slightly narrower spindle, but I don't have the experience to get specific, or even to know if it's possible. I wonder if I could take a
LHT and cold set it to a narrower standard?
