Shopping for these smaller bike bags is always challenging when you can’t pick them up and inspect them to make sure they will meet your needs. The construction is solid and nice looking. The zip seems durable and easy to use. But ultimately I won’t be using this bag. Reasons? It is just a bit too small, and that’s on me as EVOC rep did respond quickly to give me requested dimensions. But I don’t like to strap bags to my bikes (personal pref) and this bag was a pain to fasten to the top tube due to very tight elastic serving as the interior floor of the bag. That should be made easier. Finally, the company chose to set two fixed holes (matching placement on my Synapse, BTW) for the attachment points rather than the smarter slots that I normally find. Slots allow you to move the placement of the bag where you want it—closer to the stem for example. Unfortunately, the bag is short of my stem by a good 4 inches when I would prefer it to be tight. I assumed slots and failed to ask. My bad. But really…I never expected absence of slots given the high price point. Oh well. Live and learn. Summary: Bag=5 stars but the practical issues and high price drop it down to 3.
