out of curiosity... how often do you pinch flat those 23's? Mind if I ask how much you weigh? what type of rims & rubber do you use?
i'd like to plug your numbers into the interia calculation and see what I get compared to my setup
edit: interesting setup with the big ring & wide ratio cogset on back - how much do you use those lower gears?
cheers
