Very helpful. So, comparing: 1) the 56.5 top tube length with 73 seat tube angle of the Legolas;
2) the Homer's 58.5 top tube length, 72 seat tube angle, and current 90mm stem; and 3) my second-hand Custom's 57.5 top tube length,72 seat tube angle, and current 90mm stem... I think I need another 90mm stem. Let me know if I'm missing anything or my math is off. As always, thanks for the help. This forum continues to be a great resource.
