A closer look

Looks way more expensive than it is. I was honestly expecting a generic looking bag but the carbon fiber texture on this thing looks fantastic in person. It matches my matte black road bike perfectly. Hard to beat for $39.90.

Stays put on rough roads. No wobble. Bought this for my gravel bike and it hasnt budged. The adjustable straps hold it tight even on washboard dirt roads. The slim width keeps it out of the way of my knees.
Chris M. –
Great little bag. Perfect size for ride essentials. I can fit my iPhone a multi-tool tire levers and keys. Took off one star because the zipper is a little stiff when new but its breaking in.
Alex P. –
Exactly as described. Fits my frame perfectly looks super sleek with the carbon texture and holds my phone and tools securely. Doesnt rub against my legs at all.
Jason T. –
Took me less than two minutes to strap this onto my frame. The straps have a good grip and dont slide around. The carbon pattern is a nice touch and hides dirt really well.
Emily R. –
looks awesome on my trek. the carbon fiber is sick. very happy.
David K. –
Use this for my daily commute. Holds wallet phone and a small charger perfectly. Because it sits right behind the stem I can glance at my phone while stopped at a red light.
Amanda S. –
Doesnt rub my thighs! As a female rider sometimes top tube bags rub against my inner thighs. This one is slim enough that it hasnt bothered me. Docking one star because I wish it had a small mesh pocket inside.
Kevin L. –
Survived a light rain shower. Got caught in a light rain and my phone inside stayed completely dry. Obviously not fully waterproof but the material repels water well.
Timothy Harris –
Clean setup. I love how low-profile this is. I hate having bulky bags on my bike but this one blends right in with the carbon frame.
Rachel C. –
Perfect size for my cell phone and a cliff bar. The carbon pattern is really nice.
Matt F. –
Essential for century rides. Did a 100-mile ride last weekend and this was perfect. Kept all my nutrition and my phone right in front of me. No wobbling at high speeds.
Justin N. –
Great for the price. The carbon texture is a bit shiny but looks good with my matte frame. The straps are adjustable and easy to use.
Kyle R. –
Very aerodynamic. Sits nicely behind the stem. Doesnt catch the wind. My knees dont hit it when climbing. Good bag overall.
Paul D. –
Nice bag fits great. Zipper is smooth. Good purchase.
Greg B. –
Its an okay bag. The carbon look is nice but the velcro straps are a bit too long for my aero frame. Had to trim them. Holds my stuff fine though.
Steve V. –
Looks great on my bike. Good quality.
Linda M. –
Bought this as a gift for my husband. He loves it. Says it holds his phone and keys perfectly without getting in the way.
Nick W. –
Arrived missing one of the mounting straps. Very frustrating. Tried to contact support but havent heard back yet. The bag itself looks okay but I cant use it.
Jessica H. –
Sleek design. It fits my 6.1 inch phone perfectly. The straps are secure. Only reason for 4 stars is shipping took over a week but the product is solid.
Brian G. –
Fast shipping. Looks exactly like the picture. Very happy.
Oliver S. –
Top tube bag fits perfectly. Love the texture.
Chloe T. –
Super easy to install and looks very premium. It doesnt sag when you put heavier items inside. Definitely recommend.

Good bag does what its supposed to. The zipper pulls are a bit small if you have thick winter gloves on but other than that its perfect.
Will K. –
5 stars. Looks great fits great.

I have a carbon frame and wanted a bag that wouldnt look out of place. This matches perfectly. Holds my gels and keys securely.
Mia P. –
Perfect size. Doesnt hit my knees. Love the look.
Sam Lewis –
The bag is fine but the carbon texture is just a print on a plastic shell. I expected it to feel a bit more premium. It does hold my phone well though.
Jack D. –
No more stuffed pockets! Fits my keys phone and a small pump. Highly recommend.
Emily Watson –
Looks so good on my bike. Very secure no rattling.
