I hate swapping seat bags, so when I went to put together a third one (consisting of a mini-pump, tube, lever, and flat multi-tool) I tried to find another Pearl Izumi tailgate, my preferred bag. Turns out, it's been discontinued (maybe in favor of the PRO bags). However, Blackburn's model is very similar in the ways it counts. All the aforementioned items fit just fine (esp. the pump), the price is right, it's light, not garish, and has a lifetime warranty. The only miss would be lack of a reflective panel on the back, but to me this is close enough to be satisfied.
I ride a size small bike and use this primarily on my fat bike in the winter but have also used this on my road bike for randonneuring rides when you are riding long distances that are self-supported. The quality is great and after a couple of years use, I have not had any issues. I live in Anchorage, where Revelate was born and have many friends who use a lot of Revelate products on several different bikes. You will find Revelate products on bikes in the winter endurance races (ITI, Susitna 100 and White Mountains 100) as well as locals using them on their bikes all over the world (Holy Land MTN race, Africa, Baja Divide to Arizona Trail, etc.) Very durable and great for everyday use to month's long trip. I highly recommend the Revelate Design products. And this bag is perfect for the smaller rider who cannot utilize the larger version of this bag.
I had theses fenders mounted on my GT Grade and my first time out I wore my new cleated shoes but I stopped and couldn't unfasten them as I fell over with the bike on top of me. The rear fender caught me and popped loose from its mount but was undamaged and easily refit into place so that a bruised leg and ego were the only damage I sustained. Last night I took my bike out for a ride in the rain and was pleased that the fenders kept the water off of me and was channelling the spray forward and behind me. Adding the fenders to my bike was a very good move for me as they have already proven themselves to be a quality product, sturdily made, and very effective with wet road surfaces.
I find these waffles a lot more satisfying than your typical gels (and even most bars), but they are a bit bulky in the jersey pocket. If you're only going to carry one or two, they're a nice change from gels and chews, but if you're doing a long ride, it's hard to carry enough to get the calories needed.
I'd definitely recommend them as a nice option to other products.
