Review on Ibera Triangle Frame Bag: Organize and Carry Essentials on Your Bicycle! by James Small

I am very satisfied with this bag. I bought a large size to fit my road bike and it has enough room to squeeze a water bottle into the holder below (may be tighter on some bikes). It's not waterproof and doesn't claim to be, but on a couple of recent commutes (10 miles in torrential rain) it's worked pretty well. The thin outer pocket protects the larger inner pocket a bit, but you'll still need a bag, plastic sleeve or similar for papers or books. In terms of capacity, I can fit a book or two, a sandwich, some small items like bike lights, wallet, phone, etc., and some 8-1/2" x 11" papers folded in half length. accommodate. (They do not fit in full growth). This bag won't replace a basket because it's not big enough for a change of clothes, but if I drive one day a week and take my office clothes with me for the week, I can easily get to work the other four days with just this (and a small bag underneath the seat for my spare tube and levers). It makes me light and fast without the need for suitcases or panniers. Seems to be holding up well after a few months of heavy use.
