During my most recent tours through Morocco and South America I switched from a classic pannier setup to a bikepacking system.
Now I got the oportunity to test 5 different seatpost bags. Looking forward to bring them on the trails
Price 20,- Size: 3-10 l Weight:?
The cheap price becomes visible, when it comes to the mounting. The stripes to fix the bag on the saddle are made with simple seams. In compare to most other bags it only got one Velcro stripe to fix it on the seatpost. On the trail this might let bounce the bag around more than necessary and seems relatively less reliable.
Price 40,- Size: 10 l Weight:405g
With 40,- the second cheapest of the bags, but almost at the same price level at the ROSE TRAVEL (50,-). Even if 10l should fit in – and against the optical impression – it’s a bit smaller than the BeSoul and so the smallest capacity of all tested bags.
All over it looks like a budget bag with a mature concept: A simple rolling bag without any extra features. The PVC is stiffer and more heavy than the Ripstop or PP-textile on the other bags. A Velcro at the upper end of the bag allows to close it while packing, which is a simple and helpful detail.
To prevent damages on the bag I already duct taped the part where the bag meets the seat post before riding it the first time. This duct tape was completely done after about 250km. On longer rides this would be a problem pretty sure.
In conclusion I would consider the Rhinowalk as a convenient solution for the daily way to work with fair money for value. For longer rides I would recomend to invest a bit more money and go for a higher quality option. Anyway the next more expensive in my little test is the Travel Bag from RoseBikes which seems more solide and handy for one 10,- more.
Only a closer look shows some weaknesses. I know a bit about PVC sealing and it doesn’t look well made at all parts. Especially load carrying components, like the stripes to close the bag are sealed, not seamed or additional supported. That looks not very reliable.
Price 50,- Size: 8 l Weight:410g
According to the product information this bag got a capacity of 8 l. In reality it’s still a bit bigger than the BeSoul or the Rhinowalk, which should have a capacity of 10 l.
Unfortunately there is only one stripe to fix the bag at the seatpost.
Price 100,- Size: 12 l Weight:350g
The dry bag is very thin and got an specific form to fit in the cage. To replace the dry bag will be hard with everyone but the original VauDe one.
Ortlieb Seatbag L
Price 140,- Size: 8-16 l Weight:450g
Every stripe and rivet is additionally reinforced. The construction is all over very solid. The stiff construction is resistant against any deformation. Unfortunately it also makes the fitting on the seatpost a bit complicated. In compare to the dry bag system from ROSE and VauDe that plays an important role, as the bag normally is removed frequently on longer travels.
