Downunder Bag + SWIG Hydration Kit

Take your bikepacking efficiency to the next level and lower your bike's centre of gravity. This is an essential piece of the puzzle for water storage, ideal for full rigid mountainbikes and select hardtail frames (sizes M, L, XL, maybe some S) – where there's lots of space under the frame asking to be used. It's essential that you measure the space under your frame especially when the front suspension fork compresses (see specs below).
Past bikepacking events passing through agricultural land that has been wet and muddy have resulted in a high number of gastro casualties, which could be attributed to drinking from contaminated bidon nozzles.
The SWIG63 Hydration System is a cap and drinking tube that fits the Nalgene and any 63mm wide mouth bottle . A quick detach button separates the hose for quick refill. The drinking straw fits the 1.5L Nalgene and can be cut shorter. Comes with a magnetic release clip & backpack clip.
With the Downunder Bag cable tied onto your cage, it will never fall out when the Voile straps are released. Slide your bottle in and out without handling a dirty bottle - as we all know, anything under the downtube will get caked in mud and cow pat, and if you're begging for water from someone, it won't increase your chances by handing over a filthy one.
SAVE 20% with this kit compared to sourcing all the parts separately!
SPECIFICATIONS:
- The Downunder Bag fits 1.5L Nalgene bottles (bottle is 90mm diameter, 290mm tall including the cap).
- Clear plastic window to check water levels & a drainhole.
- SWIG63 full hose length to cap: 100cm. That's 10cm longer than the old version that Paper Roads currently use, which was a stretch for people taller than 165cm. If you're really tall and need a hose longer than 100cm, opt for the extra length.
-
Also includes: magnetic hose clip unit (with foam block & velcro to wrap around handlebars or aerobars), pair of 16" Voile straps & cable ties & bonus backpack hose clip.
- Source your own cargo cage. Highly recommend the Studio Forecast Cargo Cradle.
- Source your own bottle or you may have one. (Google your closest Nalgene bottle retailer).
Tips:
- Use hose clamps from a hardware store to mount your cage anywhere on the downtube. Protect the frame by wrapping electrical tape under the hose clamps.
- Not suitable for XS and some Small hardtail frames due to lack of space when the front shock goes down (the bottle will hit the tyre). Test before purchasing.
- Not suitable to mount under gravel frames. Can work inside the frame if big enough.
