You're too smart for your own good. Those secrets are not for general consumption. It's not nice to overload the synapses when folks are stressing out on 1/2" chain vs. 1" and which is stronger. Now you come along and throw another detail into the mix. Now the guys will have to figure in the relative strength difference betwen wide and narrow plates, not to mention the metallurgy quality control, rider's weight, gear ratio's ridden, which ratio used for starting from stops and general cruising, is the rider a pusher or spinner, does the rider live in flat land or ride lots of hills, crank length, etc. This stuff is far more important than the REAL issue of how the stuff rides, performance, and why the riders chose what they did for the cycling they were doing. Now look what you've done. I hope you sleep tonight. Ted Ernst Palos Verdes Estates, Ca
