While putting away a recent Zeus order from BC, I noticed I have several Zeus 170 right arms and one Zeus 167.5 right arm with no mates. I also have several extra Zeus 165 left arms, including at least one extensively milled and slotted 2000 model. Anyone have any 170 or (fat chance) 167.5 left arms they want to trade for 165? This also brings up an interesting question. The 5 mm difference from 170 to 165 is less then 1/5 of an inch, the 2.5 mm difference between 167.5 and 165 less than 1/10 of an inch. Anyone have any experience riding cranks with slightly different arm lengths? I'd think most people probably have 5 mm or more variance between left and right leg length, although it is probably random which leg is longer. Maybe I should just match the 165 left arms with the 170, or especially the 167.5 right arm.
