You pick your chainrings to center your mean cog behind your front chainring (to within rounding error), then stay in that ring. You can't do better than than that with 1 in the front. If you then shift in a chainline-optimal fashion you can only improve on that with two.<br /><br />But I'm using a "real world" example of a rider who isn't thinking much about chainline when he's riding other than to avoid extreme cross-chaining. Sure -- this is a ride probably near Paris, where it's mostly flat, but then a lot of riders do the vast majority of their riding on such terrain (New York, Chicago, Philadelphia, DC, Boston, ... most major US cities). And the result is the chainline can actually be better.djconnelhttps://www.blogger.com/profile/01484858820878605035noreply@blogger.comtag:blogger.com,1999:blog-1564958057737541664.post-16247156877302381742015-04-26T16:55:19.251-07:002015-04-26T16:55:19.251-07:00Or, maybe it means Ray needs to pick his front cha...Or, maybe it means Ray needs to pick his front chainring choice better? ;-)<br /><br />That said, since losses aren't necessarily proportional to deflection across the entire range, I'm not sure how indicative of "good or bad" the average deflection metric is.
