I cannot do a messenger bag. Tried, and I am just too short, for the size I needed. My balance is weird with things like that, in that once I get used to riding on a specific bike a certain way, I don't do well with anything that changes the feel. I am going to make myself ride the Guru tomorrow, despite the fact I don't like the way it feels to get on the bike (like I have to really push myself up onto the saddle). I can't let a custom titanium bike sit. It feels like a dream once I am riding, but the geometry on my Silque is just so perfect, now the custom doesn't feel right.
