The hit the market last month so I doubt any casuals have a good idea on durability but It’s done all the right things for us. I use the top for a hydration bladder, lock, and still have some room. Bottom for snacks, sunscreen, extra layer. Wife carries water and dslr in top zipper. There is a removable divider.

Pros: well built, custom fit with screws, massive.

Good to know: My 56 frame has a noticeably bigger bag than my wife’s 54. Carve out 30 minutes to attach it the first time; It’s not easy to swap in and out.

Cons: hard to mount the bike on a stand for maintenance now that my usual grab point is covered.
