NorthSeven Carbon Triangle Frame Bag - 100% Waterproof & Lightweight for MTB and Road Cycling | Adjustable Non-Scratch Velcro Design | Holds Large Cell Phones, Wallets, Gels, Tools and More!

I tried many bags but all were too big for my (size) small trek Mountain Bike. This one is perfect. I keep my locks in it. Also it does not damage the paint and the material of the bag is very good.

The case is large enough to hold a large Apple X in a case with room to spare for other items. Good design overall and stable while riding with it attached to the bike frame. I looked at a great many similar frame mounted bags for my smartphone and this seemed to be the best. Now with it on my bike and after many rides I am very happy with it in every respect.

I use the frame bag to carry a spare folded road tire, hand pump, tube, large multitool. Fits well on my titanium road bike.

I bought this bag for my husband as a gift. He loves it. His only complaint is the two top Velcro straps. I believe his bike frame is a bit wider then other bikes and thus the straps are a bite small and when he accidentally knocked it while riding one of the straps opened. I think if the top straps were slightly longer it would be better for stability.

This is a nice triangle bike bag that'll look good on any carbon fiber or black colored bike meant for road conditions. The design mimics a carbon fiber frame and is a rubbery type of material for water proofing. I think it's better than the cordura material one that amazon recommends. However, the straps will only fit on frames that are standard sizes. Other than that, I highly recommend it.

Nice frame bag. Stays tight on the frame. Will hold bare necessities. Mine is on a road bike, have a tube, levers, phone, keys, and small multi tool in there. Not an option for anyone looking to store a 27.5 or 29 tube. You could probably get it in there but there might be interference when pedaling. Havent used it in the rain so i cannot attest to how waterproof it is.

I had to replace my bicycle bag that attaches to the cross bar in front of the seat after the zipper broke, I purchased a new bag and it seems to be what I was looking for. Not sure how waterproof or durable it is, having just purchased it, but I am happy with the bag.

large enough to fit several items, easy to open does not interfer with legs while pedaling. inside pocket greatly helps in dividing items in an orderly fashion.
