I would be riding the 58. Yeah I mean obviously if you have a tight wheel base you have less room for your toes to clear. I just haven't ever had that problem and wouldn't really want to deal with it. Just seems like an inconvenience and when I could go pick up a bareknuckle that I have ridden before and not had that problem I would just do that to save a small amount of piece of mind.
Oh and couldn't it be a problem with track stands? I mean seeing how as I spend most of my time riding and not doing tricks and track stands it isn't that large of a problem, but could be annoying at lights.
