I love that idea. I was wondering what I might use on Bike Virginia as my new Felt FW3 has no eyelets to put a rack on and I like to carry rain gear etc in a rack bag. I have been looking for a solution since you cannot put a seat post rack on a carbon seat post. This looks like a very good solution for the things that would "bulk up" my jersey pockets too much. Great suggestion...perfect solution. Thanks so much.
