The construction of the EDCO Competition allows it to be fully adjustable for a perfect chainline. The center ring on my pre-CPSC Record triple aligns with the center cog on the 5 speed freewheel. The crank arms are equidistant from the chain stays. I use a 2mm spacer on the left side so that excess threads are not exposed. Mine is French and the spindle is 121mm in length.
