Hello,
I currently have a 2x9 with a 26/38 crank (Silver brand) and a 11/34 cassette on my Rivendell Clem Smith Jr - H. I want to add a third/outer chainring (maybe a 44 or 46), which can be done by replacing the Silver bashguard with an outer chainring. I am shopping for a replacement front derailleur (either a Shimano XT M771 or XTR M971) because I don’t think my Claris FD is capable of a 3x. I am looking at the specs of both FDs. The “Front Chainwheel Tooth Difference” is 20T/22T for the XTR and 18T for the XT The “Min. difference between top and intermediate” is 12T for the XTR and 10T for the XT How closely do I need to meet these two requirements? If I get a 46T, I don’t meet the Shimano specs. The Front Chainwheel Difference is 20T and the Min Difference between the top and intermediate is 8T. Will either FD work? I wanted to save money by leaving the 26/28 alone. On a side note, I don’t plan to use the smallest chaining (26T) very often (if ever) as I basically spinout for most of the 9 cogs.
