The new Restrap Downtube Bag is as simple and straightforward as its name implies. Yes, this is just a small waterproof roll-top bag about the size of a large water bottle that straps around your bikes frame to give you overflow storage where you didnt have any. No need for a spare set of cage bolts it can actually tuck in anywhere you have free space. So, you can strap this thing onto a gravel bike, a bikepacking bike, or even your mountain bikeRestrap Downtube Bag provides 1.2L of waterproof storage(Photos/Restrap)The Restrap Downtube Bag is meant to be strapped under your downtube really any dead space on the bike you arent using.Yes, its gonna get muddy behind your front tire down there. But it also could be the perfect spot to pack away a rain jacket or of set rarely used tools and spares that youll feel better knowing are there if you need them.The bag has been in development for quite some time, and has already been put through its paces at demanding adventure races including the Silk Road Mountain Race, Land Between, and Bright Midnight.Will it fit?How close your front tire gets to your downtube will really determine whether it will be a good fit for you. It will tuck in between your crankarms, and even behind a big chainring in most cases. The bag is about 24cm long when packed and will stick down from your frame at least 8cm. And you should leave a couple of extra centimeters for safetys sake a lesson learned from personal experience. As a rule, road & cross bikes often wont have enough space. Nor will some smaller-sized bikes or those that are really pushing their max tire size limitations. But adventure-y gravel bikes, especially bikepacking-specific bikes should have plenty of room, and most mountain bikes will too.Extra storage wherever you need itBut it doesnt have to go under your downtube either. A quick bit of bad-photoshopping fun suggests a lot more spots on Restraps Cotic Jeht trail bike that could fit an extra little bag since the steel mountain bike only has one set of bottle cage bosses. It also will sit nicely on a cargo cage, too. Im not saying that these spots are all good ideas where to stick a Restrap Downtube Bag. But Ive used a similar bag like this in the past, and definitely strapped it on a dodgy spot and was mostly fine. A small-diameter roll-top bag like this can be a pain in the butt to stuff bigger gear into, like say a rain jacket. A bit easier you can fill it with a couple of spare tubes, a tool, levers, patches, some C02s, and just swap it around from bike to bike in seconds. Any way you look at it, its really nice to be able to easily carry more gear on a bike when there arent other options. And since this pack is quite small and adjustable in volume with a wide secure velcro strap, it tends to actually be quite secure on the bike once you strap it into place.
