RNS Bike Frame Bag - Bikepacking Bag Triangle Frame Bag Bike Bag Bicycle Bag Bike Pouch Frame Mountain Bike Bag Bicycle Storage Bag Bicycle Pouch Bicycle Frame Bag

It fits a 3x6x8 first aid kit with a lot of space to spare in the big pocket. The little pocket holds a tire repair kit, a multi-tool, and a hex set. The nice, slim design fits my Trek Marlin 6 first generation like a glove. If you have a 29er, you should be fine. It's a little hard to take the straps that go on the down tube off, but once on the bike, it seems like it will never come off. It is extremely secure. definitely would recommend this bike bag.

Mounted this bag on a Salsa Beargrease Carbon size medium frame. The bag fit the triangle near perfect. The down tube straps were just barely long enough to go around the oversized carbon tube. The pack held 6 freeze-dried meal pouches and the battery for my headlight. The zipper can be finicky when stuffed and the bag is not waterproof, so you have to keep the latter in mind when packing.

5 stars for now, as this was a perfect fit for my girlfriends extra small bike. This happens to be on a REI ADV 3.1 bike, and fit flawlessly. I cannot speak for durability or water resistance yet. It is very difficult to find bags that fit her bike correctly, so this seems to be the one! Great for the price point, and as close to a custom fit as I could have hoped for. Overall seems well made and has good storage capacity even for a small bag!

Looks and fits my fatbike frame right. Enough space to use my top tube bag and straps secure to the frame. Great pack for the price

I am tantly fighting to open or close this cheap zipper. Bag probably cost $10 bucks to make, how about putting in a zipper that you don't have to fight with. Put a nice y2k in so customers can open the bagsingle handed. This stupid thing keeps getting stuck, and requires me to wrestle with it every single time.

Works fine, quality bag

Fits bike will tryout on trails for durability.
