Question: Can they be separated?
Document: these panniers are fairly small but very versatile. they CAN be used with front or rear racks. i use them on the front, and my forks are probably raked back slightly more than most. the distance btween the top hooks and the bottom of the bag is about 11 inches. i have them mounted to the 'Voyager Low Rider Front Rack'.
so i would not be concerned the nuts might come off. the strap that attaches to the bottom of the rack has 2 points of attachment to the bag and appears durable. there is a spring loaded clip centered btween the two top hooks to secure bag to top of rack. a looped hand strap centered over the clip provides easy, one hand removal. no zipper close for main pocket.
should provide more than enough protection from the elements. this bag is NOT waterproof. in the position i use them(front rack), u would have to be riding in a steady rain for them to get wet enough to allow things inside to get wet.all-in-all a very good bag . i would recommend them to anyone looking for a small,versatile set of commuting panniers for front or rear racks at a very reasonable price.i posted a couple of pics.
pretty quick.
its hard to beat this price! i cured mine with a sealant and retro fitted waterproof bag to fit over it and i have gone roughly 1000 miles without any problems. i will probably get another 20 years of use out of them and when they finally kick the bucket, well, ill just buy another pair! all ready bought another pair for my girlfriends touring rig....you get the picture?
as well as ones showing them on the front of the bike)
Yes, there are better quality bags but I'd never buy and use them. These will be on the bike whether I'm commuting, heading into town for a shopping trip (I live eight miles out in the country) or just heading out for a relaxing weekend ride. I can carry all my gear, a jacket and some food for a roadside picnic. Or being a trike...a picnic while relaxing on the trike in the country.Highly recommended!
Works great as advertised and are tough too. I would reccommend them for any bicyble commuter. They hold enough for a change of clothes, lunch, bike repair equipment, a laptop and a book to boot.
While the Avenir small panniers are exactly what the ad's explanation is, I now wish that I had gone with the larger set. It does hold my Dell laptop - but just barely.
Well worth the money. Local bike shops were offering this price for only one pannier, so this is a very nice deal. It is very easy to put on and take off, making it great for regular commuting. Haven't tested it in rain yet.
Answer: no
