the 8 speed 90speed debate has got me to really thinking yeah i know it hurts. but if anyone is good with with math maybe this question can be answered. with a 22 32 44 front crankset and 11-32 rear cassette what are the realworld gears and how many are duplicated from top to bottom on the front gears? on the granny gear you are not supposed to use the bottom 4 on the rear on the big ring not the top 3 also is there any way to calculate a rear cassette that can use all three front gears? is this a job for the mathamagicians. i cant do it help mee
