I've had the zeitgeist and saddlesack. It really depends on what you're going to be using them for. The medium saddlesack is definitely larger (18-23L) than the zetigeist (11L).
I've mostly relied on the medium (and large) saddlesack for camping and errand running along with a shopsack up front, usually keeping the saddlesack off the bike unless I know I need it, whereas the zeitgest is something I usually keep on all the time and use for long rides to keep jackets/gloves/food/etc (probably not a whole lot of rhyme or reason to keeping one on all the time vs the other, just the way it is, something about the zeitgeist being smaller i guess). More recently I realized that if I stop using stuffsacks I can actually fit my tent and sleeping pad stuffed directly in my large zeitgest along with my inflatable sleeping pad and pillow, removing the need for a saddlesack, and that combined with a front bag for clothes and food is plenty for an overnighter (i guess smaller is simpler there, no real reason other than i could). Another consideration is clearance. I'm short and ride 52cm frames and need rack support for both. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
