I have a Sakae SA Crankset on my 1986 Trek Elance 310. It's 110bcd 170mm arms with stock 40t/52t rings. It's a strange Crankset being it's a double crank but has #5 74bcd 'concave starter holes' that don't have threads tapped in. I've done this converting the crank to a triple by drilling and tapping the holes, then installing a 74bcd 28t biopace granny ring. Luckily I didn't need a longer bottom bracket spindle. There was just a 'smigine' of clearance <1mm btw. The granny ring teeth and chainstay. Very unusual but nice looking and stout crankset.
