I generally like 170mm cranks (or funky Sugino 171s (6-3/4" inches, in case anyone wonders where the "1" in 171 came from), but I switched to 165s on my UO-8 because of toe-to-tire overlap. (Mine has an aftermarket fork which puts the front wheel farther back than stock.) I still have toe-to-tire overlap with a 28x700C tire in front, but it is certainly easily tolerated and not a safety issue.
My UO-8 with barcon cables routed between the rack and the cylindrical Bellwether front bag.
