Sora also has trim. It's a little bit different with Sora though because Shimano decided that they wanted to save money and only manufacture one shifter for both triples and doubles so all Sora front shifters are indexed for a triple. I don't know if this has always been the case so it's possible that if it's older Sora it might be different.
