Something I'm curious about
: how is the XD600 different than the XD2? Prices I've seen have the XD2 as a bit more expensive than the XD600, and the forging pattern is different (see picture below) and it seems like it gets correct chainline with a slightly shorter bottom bracket spindle (107 or 113mm recommended for XD2, 113 or 118mm recommended for XD600). Anyone know where these fit relative to each other in Sugino's line, or why they both exist?
