Great quality and value. I wish I had learned about this rack years ago. We ordered these in a 13 and they fit like a 12. It doesn’t last long. We pushed on our bikes sideways to see if they would tip over. You can manually switch it, but at that point, its another step in what should have been a simple call pickup. He intentado hacer el reembolso y nadie me contesta de la empresa, dejan mucho que desear. Not remotely comfortable. Anyway, like I said at the start, take time to get used to it before wearing it out in public. Noise cancellation is not very strong but helps when you have a good seal in your ear.
