The XLAB Carbon Wing, but with all the crap attached to it. Specifically curious if anyone knows if the saddle bag that goes just under it would cause any aero drag penalty? For example, this one is all loaded up (http://www.trisports.com/...-wing-140-6-kit.html), and I know that all the stuff behind the saddle is generally drag-free, but the bag that is under it seems like it would catch some wind. Thoughts?
