I have a hidden p-clip with about 3 spacers at the BB on my Genesis Vagabond (Why U no drill BB-bridge Genesis?) this is plenty neat :D
Having somebody turn a conical washer in black delrin or something would probably get you somewhere around peak neatness though.
@Heldring Just need to ride to China now, right?
@MisterMikkel Thanks! I think I could replace (or just remove) the silver serrated brake washer and neaten it up a bit.
