Brett 12, Sidney, Lectron. BTW and all} Thanks for the discussions and very compelling arguments. I understand the concept of the gear inch, but I looked around for definitions of redundancy. What difference in gear inch's would you consider a gear non redundant (or am I preserving it to simply)? When you look at the total non-redundant gears and seek an optimum does extreme cross chaining work into the thought process? You also equate these arguments down to a final argument of “speed clusters”, could you define “speed cluster” and “progressions” . Is a tight cassette considered one that is physically narrow or is it a function of the relative diameter of one ring to its adjoining rings (ie: less of a jump).
I looked at Sheldon’s site for these answers and did not really glean them. I get the concepts you are presenting but I am weak on the nomenclature. Thanks for your patience I can only learn by asking.
