I have the Ibera Pack rack system.. ToPeak has a similar system
the Ibera rack matches well to most bikes.. and the bags you can get vary.
The Panniers you can get a midrange set or a set that is about the same quality as the Ortliebs..
I like that the bags that are set to go with the Rack fit it perfectly.
I love it.. the rack looks great on my bike.. my Bike def looks like a long hauler... and is..
The Ibera Rack isn't expensive and you can get panniers for $70 and trust me they are durable enough.. I use them for food shopping.. Ive fit tons of stuff in them..
The Trunk Bag $60 that sits on top of the rack locks in tight.. Both bags you can get rain covers.. the more expensive Pannier and trunk bags are even more durable but also More expensive Waterproof Trunk bag $80 and Panniers $140(Pair) which still isn't bad.. Just more pricey.. they come in 2 colors.. Black and Orange
