I have a set of Shimano 9 speed R600 (Ultegra grade non-Groupo short reach) shifters now on their third touring bike, a Soma Saga, Up front they run a compact triple with IRD front derailleur and in back they still run a 32 ring w/XT derailleur perfectly. I bought them used back about 2007, I think,
10 speed Ultegra is another story. I’m on my third front shifter since 2012 for our tandem.
