I'm in the process (waiting for a demo to ride) of ordering a new Vamoots and was curious about the pump peg location. I noticed on the web site that they show the peg on the seat tube when it is depicted under options and was wondering how that works. My current bike has it on the head tube which makes sense because one end of the pump lodges on the peg and the other end in the acute angle between TT and seat tube. If the peg is on the seat tube, what will hold the end at the head tube? It seems to me that it will just fall off because of the obtuse angle at the head tube. I happen to use a Zefal HPx4 pump. Just curious on anyone's experience with the peg.
