another geo related question for you - I didnt see anything in the comments above. I noticed you kept the rather "normal" STA of 73.5. I understand steep STA in the context of FS bikes where the rear sags and the steeper angle accounts for that. I dont understand why you'd want a steep STA on a HT? I observe that pretty much all the new Chromags have something like 77 (or steeper). Road bikes also seem to have ~73* STA. I know a road bike isnt a MTB but if seated pedaling power is the priority it seems like that is about where the STA should end up? curious your thoughts.
cool bike and write up!
