There is weatherproofing on the zippers for added protection and the padded insert at the bottom of the bag is a neat addition that helps to smooth out some of the bumps in the road. 

The two-zipper closure system is easy to operate with one-handed on the bike making it easy to get in and out of the bag.

The main compartment is split into two and making it a great option for carrying your tools.

There is plenty of space and the high contrast interior colour means finding what you need is easy.

This is a back to basics bag that does the simple stuff well.

The durable nylon fabric has enough weather-proofing to keep everything dry if you are caught riding in a rainstorm. 

The bag is securely attached to the top tube using the ubiquitous Velcro straps but in contrast to most top tube bags an adjustable bungee cord is used to secure it to the head tube.

  • Capacity: 0.46L
  • Waterproof? No

The Trek Bontrager Pro Speed Box is a low profile top tube bag that has just enough volume to be a useful addition to any bike.

There is nothing innovative about using Velcro to attach the bag to the top tube but the way the loose ends of the Velcro straps are routed internally means they do not flap around in the wind. 

Aside from the main compartment, there are mesh elastic pockets on either side of the bag that add to its overall versatility. 


  • Useful external mesh pockets. 
  • Internally routed excess Velcro straps.
  • Low profile.

  • Waterproof?: No

It is rated to IPX4 standard meaning that the contents should remain dry if you are caught riding in a rainstorm. 

The design is understated and elegant with nice straight edges and lines. 

Unlike most top tube bags, The ROCKBROS top tube bag is rigid and so it won’t bulge even when stuffed full of your riding essentials.

  • Dimensions: 9.3 x 4.7 x 2.8 inches
  • Weight: 169g
  • Capacity: 0.75L
  • Waterproof?: Yes, with the integrated rain cover.

The Topeak TopLoader Top Tube Bag makes excellent use of the spacious main compartment. 

For the ultimate in weather resistance, Topeak have taken a decidedly low tech route and integrated a rain cover.

If you suddenly find yourself riding through a sheet of rain, you can remove the rain cover from the pouch and protect your bag and contents.

It does, however, sort-of defeat the purpose of a top tube bag at this point.

All the benefits of quick and easy access have now been lost with the rain cover on.

Despite the roomy storage, the bright yellow interior of the bag makes it great for finding stuff even in low light conditions. 


  • Hidden pull-out rain cover for ultimate waterproofing.
  • Bright yellow interior is great for finding what you need.
  • Handy, moveable internal divider to optimise storage. 

10. Deuter Energy Bag (best budget bag)



  • Mounting System: Velcro hook and loop
  • Dimensions: 2.0 x 2.8 x 5.5 inches
  • Weight: 2.3oz
  • Capacity: 0.5L
  • Waterproof? No

Despite its budget price, the Deuter Energy Top Tube Bag looks great on the bike.

Without reinventing the wheel, it is just really useful.

The bag is attached to the top tube using a couple of Velcro straps and two Velcro straps instead of the more traditional single strap around the steerer. 

In terms of waterproofing, the contents should stay dry for around fifteen minutes in a rain shower.

In terms of storage, the Deuter Energy bag sits on the lower end of the scale and, in keeping with its overall simple design, it has just one main compartment.

This should give rough capacity for around 7-8 energy gels if you plan to carry nutrition.

There is also a small, external side-zip compartment that is ideal for storing cash and cards.


  • Reflective strips add visibility.
  • Double steerer tube straps for added security and extra compatibility.
  • Handy and secure external side-zip pocket.

Mounting Types

Most top tube bags feature a hook and loop Velcro mounting system.

The capacity of the top tube bag is perhaps the single biggest consideration for riders and wholly depends on what you plan to use it for. 

A lot of riders like to keep camera equipment within easy reach in a top tube bag and this usually means bags with a larger capacity. 

For others the top tube bag is an ideal place to store nutrition when out on a ride where a smaller bag will do.


Top tube bags are a great option because of their easy accessibility on the bike.

The stuff you need is right there in front of you. 

No matter how good the other features of a top tube bag are, if you can’t open it easily out on the road with one hand then it becomes almost redundant. 

The majority of top tube bags use a zipper system to open and close the bag but there are subtle differences between each design.

Some top tube bags have foregone the zipper altogether and instead use a magnet-buckle design.
