I'm more a frequenter in the SS FG threads but I figured I'd post this question to the guys that haul all sorts of stuff.
My bike isn't drilled for racks/panniers and I'm looking to get a fairly easy on/off type rack system for the days to work that I want to actually bring enough food/clothes/etc and not have it on my back.

I've seen seatpost racks but they are only rated at 25lbs.

Has anyone had experience with the Knog Rackless Pannier bags? Or does anyone have better suggestions other than get a second bike?

PS...On any given day I carry a widescreen laptop/cables, clothes, food, and some basic tools on countryish roads filled with gravel and bumps so I need a fairly stable system...

You could always use P-clips to mount a standard rack.

A quick release seat post rack is pretty convenient. You could split the duty between the seat post rack and a large handlebar bag.

P-clips are my least favorite way to install/remove a rack. I think you would get pretty tired of screwing and unscrewing 4 p-clips (takes a wrench and screwdriver) multiple times a week. You'll probably end up leaving the rack on.

No experience with the Knog rackless panniers. Looks pretty slick. If your widescreen laptop will fit, I'd go with that.

I drilled out a set of Tubus QR rack mounts to fit a solid axle on a FG bike with absolutely no braze-ons. Those, the Tubus seatstay mounts, and a Tubus rack have been dead solid, even with very heavy loads.

Get a low-rider, front rack to carry your heavy stuff in large panniers. This will change your steering / handling characteristics.
