Oxford X40 Tail Bag 5 5 3 3
Awesome Soft Tail Bag Easy to install. Love how secure it is with the velcro wrapped around the tail seat, and then the bungee cords to secure it even more. Great space for packing things, can even fit my riding boots (TCX S-R1) with the expanded option. Zippers are very sturdy. Easy to zip on and off the base. Once removed, the bag is easy to carry with the attachable shoulder strap, or backpack option. Only thing I'd have to say about the backpack straps - wish there was a better way to secure them down or away when I opt for the shoulder strap over those. July 8, 2016
Love this bag. I have had numerous bags over the years and find this one to be the best. Its easy to install and you can unhook just the bag when need to. You can leave the base attached to your bike and just re-zipper the bag back onto the bike. The only downfall I have is the internal liner. I feel the wet liner would be better suited over the bag and traps.When on long trips, unless you place the liner then pack, the liner doesn't do u much good. I was able to place the liner over the extended bag and it barely fit but did the trick. June 18, 2016
Fantatic bag I have had this bag for about a month and I commute everyday. This bag has great storage and is good on a nice weekend trip. The bungee system is very nice and the extra bungees work very well. All the features of this bag are worth it and give you a great bang for the buck. 2 strapping systems and can turn into a backpack make it very versitile. You will enjoy this bag, as I have as well.
