I'm looking to go on my first multi-day tour and need a rack for my Volpe. Its shorter chainstays are worrisome though, especially considering my larger-than-average foot size. I found the Jaand Expedition Rack (http://www.amazon.com/Jandd-Expediti.../dp/B000VSFHNG) which seems like it'll definitely do the trick, but are there any lighter or perhaps cheaper options available?
