Certainly don't sweat over a 1 mm chainline difference from "ideal".
Both cranks are marked "Sugino." The Centurion Lemans RS came to me with a Sugino 144 and a 52x42 chainring set. The Lemans 12 came with the Sugino 110, and a 52 x 40 chainring set. That second, 110bcd from the Lemans 12 is now on the Super Course, and that 40t inner chain ring will soon be replaced with a 36t or even a 34t ring, making these local hills a bit easier. Couldn't do that with the 144bcd, so a 110 that fits was a godsend. Thanks.
