Chainline is not an issue, unless you are a mid-century Brit... I run stock chainrings, 32/40 and the 17/19 Dos. The limitation on the Quickbeam is my Berthoud fender stays, which, strictly speaking, is not a Quickbeam issue. They could be longer, to let me use the whole range. Low-profile fasteners and a flaring fenderline allow me to use all the combos, but I rarely do. I gut things out. Huh. No problem climbing South Mountain in Phoenix, but soon I will build a wheel and play with an SRAM 9-speed internal hub... summer fun... seriously, you feel drag on the chainline? What about my internal gear friction box? Please, get an ergometer or some sort of watt-o-matic meter, and quantify that drag! Chainline is an aesthetic issue, not a drag, son. Humph... (Please don't get mad, I'm just playin'...)
