Compared to bungees and nets, straps are more secure because they can be cinched almost completely solid, which prevents loads shifting on washboard gravel or bumpy paved backroads. The 1" quick release Delrin buckle made will handle a minimum of 250 lbs. Similar looking straps sold in camping stores are too short to be useful for packing a bike and the buckles are not-quite-strong-enough. These are over eight feet long (100"), and the webbing has a 1300 lb break strength. (May be cut to shorter lengths and fuse the ends with a cigarette lighter). Sold in sets of 3.
