Apologies for the bad pun - I couldn't resist. A well-priced and sturdy wheel bag that fits a 700c wheel comfortably. The quality of construction seems good; the only potential weakness may be the zip although I've been using two of these at least twice weekly for a month or so and they show no signs of wear or failure. The bag is not padded and so won't provide the ultimate in protection for your wheels, although they do an excellent job in keeping the boot of my car clean whilst carrying the bikes on the roof. Given their attractive pricing compared to most of the competition I think they represent a great buy.
