It also has the benefit of being able to use any size stuff sack without limiting yourself to a single size bag.
without bag:
With bag
I also used the microfiber again on the inside so it's easier on the stuff sack and not as slippery as nylon on nylon.
EDIT: I'll cut that excess strap length later on. I just didn't bother for the photos.
an old (cheap) Profile aerobar works as a front rack just like this. and doubles as an aerobar too.
