Something that I've always wondered about is when and why folks switched to under the BB cable routing. I've always preferred the above routing since the cables are shorter and put them more out of the way of road grime, plus it gives the housing less bend and a better line to the RD. I can understand for production that drilling and tapping a 5m hole is much easier than soldering on two hard to jig tiny cable guides. I would think many of the custom builders would have kept it as a feature that was superior to the way they do production bikes. So can anyone clarify the history of under the BB routing and give me any good reasons to do it that way beyond it's easier? thanks, Brandon"monkeyman"Ives Sitting on the couch sunburned from surfing in Santa Barbara, Calif.
