Took this bag for a small shakedown – only 3 months in New Zealand. It took everything thrown at it without complaint. I have wanted one of these bags for years and finally have a bike that can accommodate one. The velcro straps do rub the frame so be mindful of this when fitting. Those with oversized downtubes may also find the double-sided velcro straps a short fit, but they self-adhere very well. So glad I do not have to worry about zipper failure. Used a L mtn bag on a small Curve GMX+, fits perfectly (thanks Greg for the help to getting this right).

This bag is certified “Oh-shit-what-have-I-gotten-myself-into-my-phone-and-my-wallet-are-not-in-a-ziplock-and-the-tide-is-way-higher-in-here-than-it-used-to-be” waterproof. Much to my delight it is also air tight and acted as a flotation device for the bicycle when I had to go bellybutton deep in a salty creek that was rising.
Really well designed and thought out and heavy duty this pack will be a permanent fixture on any adventure ride I have.

This frame bag is genius. First, the fit: I have a small Surly Karate Monkey (short people problems) and so not a lot of frame bags fit, but the small mountain 52Hz fits perfectly. Second, the material: the material is waterproof and bombproof and with no sewn seams, there is no chance of rain or snow entering. It’s super light too! Finally, the roll top closure is brilliant, not only because it also prevents rain or water entering, but also because the roll allows you to carry long items like tent poles. Plus no danger of zipper damage. I’ve not yet put enough miles on it to test its long-term durability, but so far, the bag looks like it will endure. The only small issue is that the attached Velcro straps could rub the frame. I replaced the removable ones for the down tube with voile straps and put racer tape underneath where the non-removable Velcro straps go (top tube and seat tube.)

I love this bag. XL fits perfectly on my XL and Timberjack. It is durable and dry and the roll top allows you to hold SO MUCH without worrying about busted zippers. I have many miles in it and it looks just as good as day 1.

Such a well made and beautiful bag! Happy to finally get my hands on one. The construction is super well done, and the new straps that replaced the voile straps are very easy to tighten and adjust. For anyone curious, and who might’ve measured 20 times and still weren’t sure like me, a L Mtn Frame fits a M Surly Bridge Club like a glove.
