However you do it, i think you are going to have to move the tabs down on the pedals because i don't think you will get enough leverage the way they are now..? the are some good articles on the Internet about brake geometry.??
My guess is you would have to lower the whole mc in order to make it work.? But if you can get shorter rods that could work. I think you will need to move the tabs down at least 1/2 ways down the pedal.?
