What is a top tube bag?

A top tube bag is a handy addition to a bikepacking kit or bike luggage setup. A top tube pack occupies the space just behind the head tube and is secured by 2 or 3 Velcro straps (or bolts).

Thanks to a teardrop shape reminiscent of 1970s dirt bikes, we often hear top tube bags referred to as ‘gas tanks’. It’s worth noting, however, that Revelate Designs coined and trademarked the name. 

While the fabric of most top tube bags is waterproof, water does enter through seams when exposed to sustained rain, due to the stitching process used to assemble the product. Thus, we recommend using an internal dry bag for contents that must remain 100% dry.

As a leader in the bike bags world, with the Fuel Tank Topeak boasts of a large storage room and a dedicated opening for earbud’s cables shouldn’t go unnoticed. 

Yopeak Fuel Tank’s one-handed operation helps navigate squirrelly gravel without lost momentum, and the zip down the middle works for quick, safe access. The bag remains solid even when opened all the way.

I rode a 100-mile century ride with the large one, it carried so much and stayed out of the pedaling. The big room lets you carry spare batteries, cables for charging, watch, bike computer, phone, travel-size lotion, chafing cream, and a few packets of Gu.

Revelate is a pioneer in the ever-expanding bikepacking bags world. When testing the Revelate top tube storage, I was looking for a bag that stays out of the leg’s way and opens at a flip. The fact that it was sturdy and spacious were welcomed pluses. 

In one go, it held my phone, bike tool, tire levers, patches, and keys. It does not rub against the knee when pedaling because of sleek design, and while riding, it has a magnetic latch for easy opening and closing. I adore it! It takes no effort and can be done in motion.

I was also surprised by how well this bag stays in place. It snugs tightly on the top tube while riding. It’s a bit pricey but well worth those few more bucks.

Aerodynamic is an important factor for professional road bikers. If you need a top-tube bag with an aerodynamic design to store tools, snacks, and the likes, then this bag is a wonderful option. It’s quality made and has insignificant weight.

The bag carries little but is aero design is ideal for race day and training on your road bike; perhaps you will find it a slim bag useful for carrying a tube, few tools, and CO2 cartridges. It has no room for an iPhone though – yes, that’s how small it is!

Using water-resistant materials for its construction, it is fully padded and insulated (note: it does not have sealed seams so small amount of water still percolates). 

By minimizing wind resistance, its streamline design supports speed. It adopts ultralight fabric, which is 30% lighter than the same thick polyester materials.

Oh, did I mention it has a sleek design? Yes, it does! At one go, people have used it to carry an iPhone 6, a snack baggie of gel chews, cut pieces of energy bar, a packet of electrolyte powder, and a tube of lip balm.

The most important quality in a bike phone mount bag is touch screen sensitivity. This bike phone mount bag does a great job in this regard and is one of the best top tube bags for road bikes. Plus it is quality made and stylish.

Surprisingly, it carries a lot too! Its adjustable Velcro straps accommodate a wide range of bikes.

With a TPU transparent touch screen case, this bicycle phone bag allows you to see the screen clearly and operate your smartphone without taking it out while riding, using GPS, using Strava, using maps, or answering phone.

Another nice top tube bag with a phone holder. The big selling points of this tube bag from Waterfly are a sensitive touch screen, waterproof material, hidden earphone hole, and reflective tape. 

The touch screen face responds to a slight touch, and a headphone cord will snake through the hole at the base. Its reflective PVC edge, which is visible in the dark, enhances night cycling.

The case is compact but fits keys, wallet, and sunglass. It’s rigid and stays out of leg’s way while riding.

Some people prefer their phones on the handlebar, but there’s no denying a tube bag like this offers better protection.

Any layman can install it, and it will secure your belongings properly. Because of the sunny hot weather on the day we tested it, however, and the fact that we neglected the fabric screen cover, the phone overheated (after approximately 7 hours of use, so not surprising!). Use this product with intelligence, and you will find it great.
