Help me calculate chain link/wheelposition length:
Will a 50T chainring on a 15T cog with one extra chain link added, put the wheel in the exact same position relative to the BB as a 48T chainring on a 15T cog .
Bonus question: 1 complete chain link is (2x1.27 centimeters)=2.54cm - so adding 1 teeth on the rear sprocket will move the wheel position (1.27/2)=0.635 centimeters closer to the BB?
