## Description

XLAB Stealth Pocket 500 C – Bolt Mounted Aerodynamic Top Tube Bag for Triathlon and Gravel Bikes

Review: Recommended - Sleek design. Mounts easily to top tube. Capacity is sufficient.
Review: This is a great add to a triathlon bike - This is a great add to a triathlon bike. Slim design does not exceed top tube width. Easily holds 5 gels (6 would seem cramped). Easy access zippers. Material seems to be good for sweating and spilling sports drink on. Makes accessing food much easier in aero position, and since tri jerseys/suits have small pockets compared to cycling jerseys, the extra nutrition space is really helpful.

## Features

- Versatile and Easy Access – Mounts directly behind your bike’s stem, providing quick and easy access to nutrition. Dual SUPER-SLIDE zippers with a non-slip rubber zipper pulls help you open the bag from either direction and with quick, easy access.
- 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.
- Material and Spec – Non - porous nylon exterior. Reflective silver lining. Proprietary insulation material. Anti-slip base. High stitch count embroidery. Volume: 0.69 liter (42 cubic in)), Weight: 101g

## 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.
