Another good write up Jesse, thanks again.
I know a few running the 415 (I'm sure Greg knows quite a few more) and am considering it myself. The only downside I can see is much faster chain stretch and replacement as you mention. The reduction in rotating mass is undeniable, which should result in better acceleration. If you or Greg can post any info concerning weight of rider, chain and sprocket replacement intervals, frequency of breakage or chain adjustment - that would give a better feel for what the maintenance trade-off would be. I'm at about 200 geared up and my only real concern is the possibility of throwing (ie; breaking) a chain and it hitting someone or me wadding up. (I make that chain work harder than a 95 lb rider would).
