A few days ago I was in need of a pair of panniers for my errand bike. It has a Pletscher rear rack which is not very pannier friendly. The bags I was able to find at my LBS would have set me back about $80, and would have required a different rack as well, so I went in search of alternatives.
I wanted something I could swap between bikes in a few minutes if necessary, and I wanted something cheap. Then I remembered being at Tractor Supply to purchase sunflower seeds recently and while browsing, noticing a pair of Weaver cordura saddle bags in the equine section (don't know why I was in that aisle, horses and I do not get along). Anyway, I returned a few days ago and bought a set. I have used them 3 times now for various errands. I really can't find anything wrong with them as long as the bike has sufficiently long chainstays. Here are some photos - $29.99 before tax.
