## Customer Reviews

### ⭐⭐⭐⭐⭐ Good for race day fuel
*by  on Reviewed in the United Kingdom 30 March 2026*

Bought as a fuel storage solution for an upcoming 70.3. Can fit 4 gels and 5 energy chew bars comfortably. Great for the price. Really handy being able to move / remove the straps so you can get a good fit on your frame. It is very slim and can just about squeeze a phone in, so if you’re looking for commuter storage I’d try something else.

### ⭐⭐⭐⭐⭐ Sacoche très pratique!
*by  on Reviewed in France 1 October 2024*

Elle s’ajuste facilement et s’adapte correctement sur le cadre de mon vélo.Très bonne contenance, suffisante pour une sortie assez longue.

### ⭐⭐⭐⭐⭐ mein ständiger Begleiter
*by  on Reviewed in Germany 22 January 2026*

.. der nützliche Utensilien wie zB.: eine kl. Powerbank, Flickzeug und/od. Verpflegung griffbereit hält. PS: und nebenbei die Aerodynamik hinter dem Steuerkopf etwas verbessert 👍😉
