I saw those, do they have the "Cross-chest load stabilizer"? how much do you recon you could fit into those? does it feel like its going to last?

irclean - I've got a rack on my old steel road frame (and I do love it), but the bike I'm using for commuting doesn't have any mounts for a rack, and I don't like the idea of having a rack mount onto my seatpost, plus I like to bring my bag into work and not have to worry about detaching stuff from my bike (which I guess I have to do regardless so it doesn't get stolen).

(work doesn't let me bring my bike inside because it will make the floor dirty).

I'll have a look through the rest of the links everyone has posted and hopefully find something to get.

Thanks !
