Hey did you ever get any answers to this? I'm looking at the same options for my STT but would like to go with the Ulysses mounts as I think it looks better. There are a few users on here who have done that swap on the SS if you look around. What I'm needing to know is what all is needed to do the swap from anyone who knows. Do we need Ulysses shifter lever and brake lever? From comparing the two bikes online I can see ether a drop bracket or the whole shift lever is different between the two for sure. I've messaged a user on here and if he gives me any info I'll post it in here for others.
