The only suggestion I would make is that the racks should have some kind of rubber footings so they don?t move around as easily. easy install just plugged in with the headphone and works. The Bad: As others mentioned the bolt holes were off. To connect a womans or kids bike (or a bike with a fat top bar or no room between top and bottom bar, like full suspension bikes), you will need bike rack top bar adapter (under $20). The hooks a very strong it?s impressive. Very good quality for the price. It is a little tricky to rewind since it is three taps. I will wait and hope it returns. I will definitely buy again from this designer. Similar to the flyknit on the Ultra Boost, these are nice and breathable, but include a combination of several different fabrics and rubber lines to help lock the foot down.
