I was at the vault and I seen these Ducat I fives for $89. I have picked up fives and looked at them but never really tried them on. I tried them on and they fit really good for a small frame. I guess the stems have a good stretch to them. It's weird because gas cans don't fit to well and they are bigger. I looked up fives on the o review and they have a long lineage. I passes on the motorcycle gp ones, so if I see them again I will definitely pick them up. I might try the 4.0 as well.
