How Do I Make a Road Crank (DA 7400) Get a Straight Line on a 120mm Chainline?
Looks like I might have 2 DA 7400 sets soon and so one will go on the singlespeed. But my only problem is the spindle length is 112mm for the crankset normally used for road, how do I calculate what size spindle I need for a 120mm frameset? Or should I just mount the chainring on the inside with a chainguard on the outside (not a bad idea) and a seatpost inner chainring ring retainer (even better)?
