I have a Clem Smith Jr. "L" bicycle. It has a SILVER crankset 110/74 bcd with rings of 34T and 24T. in the rear I have a SunRace 14-42T 9-speed cassette. There is a chain guard on the outer part of the chain rings on the 110 bcd position. I do have for the rear 9-speed drive train a Shimano M591 long caged derailleur with a Wolf Tooth road link. This works for me very well.
However, after reading the business owner of Anolog Cycles, James Johnson's article "Turkey Vulture Gearing 101"( https://analogcycles.com/blogs/news/alternative-gearing-turkey-vulture-turkey-vulture-supreme-turkey-vulture-loco-supreme), I got to thinking about what I had in my parts drawers and what was available online for purchase of a front derailluer. I came up with following: I have a 172.5mm T. A. Zephyr triple crank set - 110/74/58bcd. I also have a Shimano CX 70 front derailleur. I do have for the rear 9-speed drive train a Shimano M591 long caged derailleur with a Wolf Tooth road link. I have a SunRace 11-40T 9-speed cassette in the rear. I bought a SILVER chain guard for the 110bcd from Rivendell Bicycle Works. I placed a T. A. 36T ring on the 74bcd and a 20T ring on the 58bcd. Unfortunately, I, too, have not tried in on my Clem Smith Jr. "L" bicycle at this time, due to the fact that I am not planning to scale any large hills here in the near future. I have been riding on pavement most of the time. This link might help you, Max: https://groups.google.com/g/internet-bob/c/mFf6IERVQ_k/m/TEuNok2TAAAJ Kim Hetzel Yelm, WA.
