Hi, All, If low tread width is a priority and you really want wide-range gearing, then the TA pro five vis, fiddly setup and all, is the leader, followed by its imitators (and it's inspiration, the stronglight 49d). I can set up a 1x+granny like a 48/32 with a 140 tread width without too much trouble.
For current production, the René Herse crank is lovely, expensive, sets up well (use a Shimano 107 bb) and has a 142mm or so q. Lots of chainring choices, but only two paired setups with ramps and pins. The IRD Defiant is utterly simple to set up and live with (I can use a 107 bb on my Road Sport and the IRD is a good choice), is not terribly expensive, and also slots in with a reasonable tread width. It also comes with 46/30 rings with shifting aids, which do help with wide-range front setups. If you can live with racing gears (53/39, 52/42, or similar) then the Dura-ace 7400/7402 cranks, Campagnolo record/nuovo record/super record and their many imitators, and the lovely Suntour Cyclone/superbe cranks are great and all slot in in the 140-ish millimeter tread width range for modern chainline setups. Good luck, and let us know where you go with the bike.
