Use the space inside your bicycle frame with this hard-shell triangle frame bag. Its PVC shell and internal mesh pocket organize small essentials without using the handlebar or saddle mounting area.
- Carbon-fiber-look hard shell gives the triangular bag a defined shape.
- Wide zippered opening and inner mesh pocket make packing easier.
- Adjustable straps attach the bag beneath the top tube and beside the seat tube.

This is the first frame bag I’ve tried that doesn’t rub against my legs. The narrow profile on this hard-shell design is a game changer. Highly recommend for anyone with wider thighs.
Sarah M. –
Finally a frame bag that doesn’t make me choose between storage and hydration. It sits high enough in the triangle that I can still use my large water bottle on the down tube.
Mark K. –
I keep my phone and sunglasses in here. The hard EVA shell means nothing gets crushed when I stuff my bike into the car or hit a bump. Way better than soft fabric bags.
Jason P. –
The zipper goes almost all the way around, so it opens really wide. I can see everything inside and grab my multi-tool easily without dumping the whole bag out.
Amanda L. –
Straps are very secure. No movement at all on bumpy roads. Looks sleek and feels durable.
Chris T. –
It fits perfectly in my commuter bike’s frame. Holds my flat kit and wallet. The internal mesh pocket keeps things from rattling.
Kurt Bennett –
Good bag, looks nice. The straps are a bit stiff at first but they loosen up. Holds everything I need.
Emma W. –
The carbon fiber texture matches my frame perfectly. It looks like it came stock with the bike. Very impressive quality for the price.
Tom H. –
The quality is great and I love the hard shell, but it is a bit tight on my small 49cm frame. I had to adjust my bottle cage slightly. Still a great bag.
Jessica C. –
Holds my phone, wallet, keys, and a multi-tool easily. The triangular shape is perfect for maximizing space.
Brody Sanders –
Fits my medium frame perfectly. Doesn’t interfere with pedaling at all. Very secure.
Olivia D. –
Love that it keeps its shape. Even when empty, it doesn’t sag and hit the pedals. Good zipper quality.
Nick R. –
The bag itself is awesome. The straps were too long for my thin steel frame tubes, so I had to trim them. Not a big deal but worth noting.
Rachel T. –
Used this on a 50-mile gravel race. Stayed put, didn’t rub my legs, and kept the dust out of my phone. Highly recommend.
Ryan F. –
Feels premium. The stitching is solid. The hard shell protects all my gear. Great purchase.
Sophie G. –
The bag is very sturdy and looks great. However, the zipper is quite stiff and hard to pull with one hand while riding. Needs to be broken in.
Lucas V. –
Fits all my ride essentials. Looks great on the bike. I love that it’s splash-proof too.
Mia N. –
The way it shapes around the frame is very smart. Doesn’t get in the way of my knees or my bottle. Highly recommend.
Chloe A. –
Good bag but just a heads up, a very large phone (like an iPhone Max) with a thick case might be a tight squeeze. Fits my standard iPhone perfectly though.
Ethan J. –
No rattling, no swaying. The straps hold it firmly in place. Looks super sleek with the carbon pattern.
Sam L. –
Put this on my hardtail mountain bike. Handles the rough stuff with ease. The hard shell keeps everything safe.
Grace Phillips –
Very well constructed. The EVA material is tough. Highly recommend.
Jerome Webb –
Carbon look is great. Fits perfectly. Very happy with this purchase.
Liam H. –
Does what it needs to do. Fits my tools. A bit smaller than I expected but still very useful.
Zoe M. –
I always had issues with other bags rubbing my thighs. This one is narrow enough that it doesn’t bother me at all. Very comfortable.
Emma T. –
Looks way more expensive than $35. Very sturdy and looks good on the bike.
Mark A. –
Holds my phone, keys, and a cliff bar perfectly. Easy to install.
Daniel Foster –
Easy to install. Doesn’t move. Looks good. The mesh pocket inside is a nice touch.
