Review: Great product - Great and simple bento box ideal for storage of tools etc. fits snuggly on the top tube.
Review: Does a job - Able to get a compact pump, 3 levers, small patch set and tool kit or mobile. Usually able to fit in a gel pack as well. Velcro straps are ridiculously long! Will need to be cut to length. Seems reasonable well made, for cost. My only criticism is, it will, even with stem strap tight, want to slip sideways a bit. But value for money, definitely.

## Questions & Answers

**Q: What are the dimensions of this bag? Could a small tire pump fit?**
A: A very tiny pump might fit but it's really intended for snacks to be used when cycling; however I would put my tire pump in a saddle bag which is accessible when I stop cycling, and reserve a top tube bag like this for things I need when cycling.

**Q: Would this fit on a mountain bike?**
A: Its fits my Mountain bike.
Cant get alot in it.
Phones, keys and one or two glucose satchets

### ⭐⭐⭐⭐⭐ Great product

### ⭐⭐⭐⭐ Does a job
*by C***N on 16 May 2024*

Able to get a compact pump, 3 levers, small patch set and tool kit or mobile. Usually able to fit in a gel pack as well. Velcro straps are ridiculously long! Will need to be cut to length.

### ⭐⭐⭐⭐⭐ Just enough space for the essentials!
*by R***Y on 20 December 2024*

I got this to pack some essentials like a spare inner tube and levers etc, it's a nice size and fits nicely on the bike. The velcro provided was super crazy long so you will probably need to trim it down. Does what I need and looks nice as well! Seems pretty ruggedly built and the zip is great.
