Since I built using mostly Shimano or Shimano-compatible groupset parts, their techdocs archive was a goldmine, particularly the dealer manuals and compatibility charts. The site navigation is horrendous but the information is essential.
I’d still recommend the Leonard Zinn but note the most recent edition is 2016, may have omissions for current wheels and groupsets.
