Saddle bag works great! The only thing I noticed is that the strap that goes around the seat post barely has any Velcro holding it (my post is pretty skinny), but it works well enough. The size of the bag is very small, which I knew before I bought, but other buyers should be aware that you shouldn't expect to fit a bunch of your things in here. I can fit a spare tube l, tire levers, a granola bar, and my car and house key, but it's packed to the brim.See full review
