I don't know if this rack has been discussed before. I recently purchased a xootr crossrack to use with my brompton. I got tired of wearing a backpack while riding and the brompton can't really accommodate panniers on its rear rack. I didn't want to spend money on the brompton luggage systems because they were expensive and they didn't have a bag that was large enough for my use. Xootr had this rack along with a massive bag and safety lights for under $100. THe rack fits my brompton perfectly. I would recommend this rack to anyone, especially to people with folders because our bikes are quite unique because of the folds and I think this rack will accommodate many types of folds.
