I have never written a review on Wiggle or on any other sites, but I feel compelled to write this one as I think this product is flawed and you are better off spending more money upfront for other products. I bought one of these after a lengthy research, I was attracted to its design and ease of packing a bike. Before the whole thing fall apart, I had used the bag for 2 trips and I was quite happy about it. But during the 3rd trip, both of the bladders were deflated and it damaged my rear derailleur. As you can imagine, it was not a pleasant experience especially when you are going on a cycling trip. In addition to that, one of the wheels also came off. We are talking about a product that you paid almost US$ 600 for. I ended up contacting Biknd and after multiple emails, they sent me a replacement bladder and a spare wheel, but the wheel was so difficult to replace I ended up not replacing it and the bag is sitting in my store room while I bought another new bike case. In short, I would not recommend this product to anyone.
