Volsung, I emailed Pat to see what size his Vaya is. Still waiting for a reply. I believe it's a 57/58cm frame as Pat is almost as tall as myself.
I chose a multi-position/universal mounting system with my SnakPak's because of situations like yours. Sewing the velcro on permanently caused too may headaches.
Hey all, Just a heads up that J.Paks is offering up free shipping this weekend. He doesn't do many deals, so if you've been thinking about it, now is a good time. JPaks.com
I ride a small frame. where do you put your water bottles ? Seems like the frame bags take up most of the space? Maybe you are just using hydration packs
