How to Choose the Best Top Tube Bag?
Top tube bags come in all shapes and sizes, and not to mention the vast number of features. It’s quite difficult to decide on a decent top tube bag. Here’s a list of everything you need to know to buy the best top tube bags for road bikes, moutain bikes and more.
Easy Access and Opening System
Check where the top tube bag is meant to be placed. Some are meant to go under the tube, which can make access a bit harder. Many new models also come with phone holders that let you interact with the touch screen.
Most top tube bags open using a zipper. Make sure the zipper is metal and opens smoothly. If the manufacturer mentions that there’s a strip of nylon under the zipper, then it will most likely zip up smoothly.
Also make sure the zipper is from front to back, not top to bottom. This way, your objects won’t fall when you open the bag.
Check Size and Capacity
Next, consider the size and capacity of your bag. Most bags state which types of handlebars and top tubes they are compatible with. Top tube bags, except for the phone holding ones, shouldn’t be too wide, as this will interfere with your cycling.
Capacities can range from 0.5 liters to up to 5 liters. Mostly just 1 or 2 liters is enough to secure your phone and wallet. 5 liters may be needed if you have a lot of cargo such as multiple devices and water bottles. But it’s not mandatory.
Waterproof and Dustproof Features
Many top tube bags resist water and dust damage. This is usually in the form of a higher denier of fabric, polyester fabric, or a PU coating. Some may also use a silicone sealant on the zipper for added water protection.
You should always test your waterproof top tube bag before taking it out for a ride. Put a dry piece of paper or tissue in it and completely soak the bag. If the paper or tissue gets wet, you should know it’s faulty.
This is important since you’ll be having your phone, money, and even spare batteries in there.
Also, take a look at the material of the bag. Most top tube bike bags are made of a certain denier of nylon. The higher the denier, the denser the weave will be. Some may also use polyester due to its natural waterproofing abilities.
But some use a combination of the two. Some tube bags have a special closed-cell foam padding around the sides to help the bag maintain its form. Always do your research on the benefits of the material before buying a product. They not only decide how secure the bag is but also the possessions it houses.
Top Tube Bags Weight
Finally, consider the weight of the top tube bag. This isn’t a big issue, but some bags can weigh down your bike. You want a bag that’s no more than 6 pounds heavy. Preferably, go for the one that is as light as one pound.
The weight will increase as you add more stuff into it. But a lighter initial weight will help minimize the stress your bike has to handle.
