Thanks for that suggestion!

I'll def be running external battery for now, but the promise of a clean front end is alluring. Alluring enough that i'll consider having the EW-67 on the outside in the BB area.

I'll be the first to admit that this whole exercise is akin to Cap'n Ahab hunting the white whale as it is more than just slightly quixotic. I can contently accept defeat when guys beat me by more than three minutes in a 40 km TT on a worse equipped bike ;)
