David provided the best outline; we leaned on him to hit the criteria we set. As you say, boost cranks are a hurdle we did not want to accept. In fact, we wanted a narrower Q-factor than we have on our other "normal" gravel tandem. David at Granite was able to configure the bike at 156mm stoker Q-factor in back, and a little less for the captain. I think we have about the tightest clearances from cranks to stays, chain to tire tread, and mud clearance for both the 29x2.3 and 27.5x3.0 as is reasonable and reliable.
