Great bag, runs small

Great frame bag. Solid build, but the sizing listed isn't the correct sizing. It is listed at 18" for the size med, but it comes in at 16.5". That last 1.5" would really add a lot more capacity. I love the ability to unzip the bag when you need more capacity. The only problem is that when the bag is really loaded up, the bag can bulge out a bit and cause some rub on your legs.

Good capacity

I've used it several times

This bag offers pretty good capacity. Without the bag fully extended I can still carry two water bottles via bottle cages. In that configuration I can put a jacket and plenty of other necessary items for long rides or overnight trips. It mounts stable to the bike without issues.


Can you verify the length of the medium frame bag. I was told that the specs were wrong and the large is actually 18" long. The Medium is 16"? Could you double check somehow?

Wish I'd read this earlier! I just got a medium from another store. The bag I received measures 16 inches fully stretched - nowhere near the 18in claimed on the packaging.
