Not sure why I hadn't setup the synchro shift on this thing yet. Figured out it has the bluetooth connection and can use e-tube. That's cool. I hear just to never let it update the firmware, haha. I didn't let it. But that synchro shift is freaking cool, especially for a TT bike given that when you go big ring to small you're likely taking your hands off the extensions and going to the base bar at the same time as you're slowing up a hill.
