I am not huge on having large packs or saddle bags on my 2011 Trek Madone, but when D2R sent over a couple bags to try out, I was won over. With the D2R Rear Bag easily clamped to my seat post, it made carrying my normal load of tools and tubes a non-issue with adding some extra gear for changing once I arrived at a destination.
Attaching this rugged bag to your seat post or on top of your rear rack for extra cargo capacity on long rides is a cinch. Big enough to hold enough gear for an all-day adventure, the Rear Bag includes an interior zippered mesh compartment and key fob. The included seat post attachment system is compatible with carbon-fiber seat posts.
It is 195 cubic inches with 12 x 7 x 6.5 inches of great looking design and space. Priced at $85, I would call this a worthy investment in carrying some gear around on your commute and or road expeditions. Get one at their website today!
