Carrying gear on a short wheel base recumbent (SWB) is difficult. I have found it especially difficult on the Cruz Moose but perhaps the Apidura pack is the solution. The Apidura mid-pack is holding everything needed for a PBP type trip in one nicely wrapped package. In fact way more room than I need for a sleeping bag, clothes, rain gear, and tools. The pack is designed for the seat post of a diamond frame bike but so far it is working very well on the Silvio. More miles will tell.
