Thanks. there's a pile of DA Di2 and an ultegra chain and cassette sitting in a box in my garage now, installation is next week.
I'm going to have my frame drilled to get the front half of the wiring inside. Anyone want to talk me out of that? I don't care about the warantee, just don't want it to uh... asplode. wow, finally a context in which to use that word.
