Bikes: '96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '20 Surly Midnight Special, All are 3x10. It is hilly around here!

Is the 110 bolt circle part of the large chainring? Other than MTB cranks I've never seen what you describe and the only two bolt circles I've ever seen are 135/74 (Campy), 130/74 (Shimano road) and 110/74 (Older MTB and touring/trekking cranks).
