## Description

## Features

- Secure, Worry - Free Installation – Securely and quickly bolts onto your bike’s bosses. Designed with soft, non - slip surfaces where the bag meets the frame. This lets the bag rest gently against the frame without scratching or damaging it. Easily removed for cleaning. The bag’s rounded nose and tapered tail are a good option for bikes with brake and shift cables that enter the frame directly behind the stem.
- Smart Storage: The sleek, element-deflecting exterior provides additional protection, durability. Makes it easy to wipe away nutrition residue or condensation. Insulated sides + a plastic stiffener help slow down heat build-up or the frozen cold all while protected from accidental hits. Large enough to carry 1 large nutrition bar and 5 gels or up to 7 gels.
- Increased Aerodynamics: Mounting the bag directly behind the stem or cables reduces overall drag caused by your stem and headset spacers. The overall shape conforms to the 5:1 airfoil ratio resulting in a streamlined low drag aero profile. Reduced drag mean more speed with less effort.

## Questions & Answers

**Q: How does it attach to the bike?**
A: Screws

**Q: will this hold 2 tubes and tools to change a flat?**
A: It easily holds 1 tube, two spoons, a CO2 cartridge and an air chuck. I am sure I could get an extra tube in it but I save that space for a gel or 2.

**Q: Can it hold a smart phone?**
A: I just dug out one of my earliest iPhones (generation 1?) that measures 4 1/2" x 2 1/4".  It does fit but I haven't seen anyone using this old of a phone in years.  If you go any bigger than this...it won't fit!  I have one spare tube, X2 air cartriges, 1 tire lever and I can probably cram in 2 gel packs.  I do like the design on THIS case and it does what I need...but it wont fit any of the never cell phones.

**Q: Why does the product title say "strap mounted" when the description indicates that it is to be bolted on? Which is it?**
A: Hi, thanks for reaching out. This is supposed to be BOLT MOUNTED. Some other seller must have changed the title. We are working on getting it corrected. Thank you for bringing this to our attention.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Small but useful
*by N***E on April 20, 2024*

The bag connects to your bike with screws. I add protective tape on the bike first so the bag wouldn’t damage the finish and reinforced the bag with large washer to ensure the screw heads don’t wear though. Great setup, study and useful. Even added Velcro to secure a tubular battery within bag to keep phone charged on long rides.

### ⭐⭐⭐⭐⭐ Aerodynamic doesn’t get in the way
*by L***A on August 1, 2024*

We bought these for one set of bikes and went and bought them again for a second set of bikes we absolutely love them.They are small, but they do not get in the way

### ⭐⭐⭐⭐⭐ Quality materials
*by M***T on June 9, 2023*

The media could not be loaded. Nice materials but I would have preferred a single zipper. It’s a nice place to stash an apple AirTag!
