They offer some trekking branded groups, so the only indication is that they don't consider the drop bar touring market worth catering specifically for. Have they ever?
I don't think they do or ever have,but conicidentaly Shimano 3x9sp worked very well for dropped bar touring enthusiasts,but went out the window with the advent of 10sp along with the dropping of triples in the higher end groupsets,though Stonglight Impact and Spa Cycles filled the gap,along with lower end Claris and Sora triple STI's or bar end or DT levers.
The design specifics of many Shimano components make individual tailoring of gear ratios a bit of a gamble. I have tried to change cassette ratios and chainring sizes on 9 and 10 speed systems and failed to get them to run properly. That was something that was very easy to do on 1st generation index 7 speed.
They can have their problems depending on positioning of ramps on the out of sequence individual sprockets.
I'm currently in the process of trying a 12-26(12,13,14,15,17,1,9,21,23,26) Sram PG950 cassette splitting it,ditching the 12,13t cogs,replacing the 14t with a 14t Shimano top cog from a HG400 14-25t, and adding a 30 and 34t from a Shimano Deore HG on the low end to give me the range.This will keep all sprockets in sequence.
I'll report back after testing
