I was wondering what you ended up with! Looks cool.
Both are seamless transitions. First is Ti/carbon.
Thread is here.
Second is aluminum and carbon. Cannondale SystemSix Barloworld Team Rep frameset. It's been stripped (Campy was donated to the Holland) and is just a parts hanger currently, but trying to sort out how to rebuild it.. It's been 9s Record, 10s Record, 11s Chorus - Gotta figure out what I wanna hang on it next to actually ride it..
