Buying Guide: How to Choose a Top Tube Bag for Bikepacking
Picking the right top tube bag for your bikepacking or touring setup is more than just grabbing the first one you see. I’ve found that a little forethought goes a long way in making sure your bag is a helpful companion, not a constant annoyance on the bike. The first thing I always consider is capacity and size. Top tube bags are meant for small, frequently needed items—think snacks, a multi-tool, your phone, or a battery pack. You want it to be large enough to hold your essentials but not so bulky that it interferes with your knees while pedaling. I measure the space on my top tube to make sure a bag will fit comfortably before I buy.
Next up is the mounting system. This is a big one. Most bags use either a velcro strap system or a direct bolt-on mount. Velcro straps are super convenient and easy to move between bikes, but I’ve had them shift a tiny bit on really rough terrain. Bolt-on bags are incredibly secure and stable, which I prefer for rugged off-road touring, but they require a dedicated mount installed on your bike’s top tube. Some bags even offer a hybrid system, which gives you the best of both worlds. Also, check how the bag opens. A zipper that runs along the top is common, but I really like the ones with a magnetic or fidlock buckle for super quick, one-handed access to my snacks while riding.
Material and construction are what separate a bag that lasts one trip from one that lasts for years. I look for bags made from robust, waterproof materials like X-Pac or heavy-duty Cordura nylon. A waterproof zipper or a well-designed rain flap is a must-have feature for me; there’s nothing worse than reaching for a soggy energy bar. Finally, don’t forget about the little details. Does it have a passthrough for a charging cable? Are there internal organizers for smaller items? Is there any reflective trim for visibility? These are the features that can make a good top tube bag one of the best top tube bags for bikepacking & touring for your specific needs. Taking the time to think about how you’ll use it will ensure you get a bag that makes your ride better, not more complicated.
Frequently Asked Questions
What size top tube bag should I get?
This really depends on what you plan to carry and your bike’s frame geometry. For most people, a bag in the 0.5 to 1-liter range is the sweet spot. It’s large enough for a phone, snacks, and a small repair kit without getting in the way. If you have a smaller frame or a very aggressive riding position, you might need to go with a smaller, more streamlined bag to prevent your knees from hitting it. I always suggest measuring the length of your top tube’s flat section to get an idea of what will fit.
Are bolt-on or strap-on bags better?
Both have their place. Strap-on bags are versatile and easy to move between different bikes, which is great if you have more than one ride. Bolt-on bags are the winner for pure stability and security, especially on chunky, technical trails where you don’t want any bag movement. For long-term touring where the bag will live on one bike, I lean towards the bolt-on option for its rock-solid feel.
How do I prevent my top tube bag from scratching the frame?
This is a common and valid concern. Most quality bags will have a soft, non-abrasive material on the backside, like a soft fleece or rubberized coating. You can also add an extra layer of protection yourself. I’ve used clear frame protection film, like helicopter tape, on the contact points before installing the bag. It’s an invisible shield that works perfectly to prevent any scratches from dust or grit that might get trapped between the bag and the frame.
Can I fit a large smartphone in a top tube bag?
Absolutely, but you need to check the bag’s specific dimensions. Many modern top tube bags are designed with a large phone compartment in mind, often with a clear window on top so you can use your phone for navigation. My advice is to look at the internal measurements of the bag and compare them to the size of your phone, especially if you have a larger “plus” or “max” model. You want to make sure it fits comfortably without putting pressure on the zipper.
What is the best way to organize a top tube bag?
I like to keep it simple. Since it’s your go-to spot for items you need while moving, organization is key. I use the main compartment for bulky items like snacks and a battery pack. If the bag has internal elastic loops or smaller pockets, that’s where I put my multi-tool, a tube of sunscreen, or my keys. Keeping things in consistent places means I can find what I need by feel without having to look down and stop riding. A well-organized bag is a core part of a successful setup for any of the best top tube bags for bikepacking & touring you might be considering.
