so smaller inner ring is at the bottom, bigger, further up.. advantage is wide choices of gearing..
somewhat like old TA, but not it's 11 little bolts and older, 50's, design limiting shifter options.
I prefer Jan Heine's Rene Herse double crankset with 3 bolts that is being sold through Compass cycles. Some of the best cranks and flattest rings that run so true you won't have run outs when shifting at the extreme! I have a pair of Sugino Super Maxy cranks and thankfully for old school good quality forged cranks, it runs pretty true with little run out.
