Not Meant for Short Riders

I've put it through the wringer

For any of these backloader is not meant for short riders. If your seat post is not high enough it will rub on your rear wheel. I had barely enough clearance (about two fingers apart) from my rear wheel to the bottom of this bag. On very bumpy gravel roads I had to stop and readjust the bag a few times. I also tried several ways to pack items inside (with heavy items in first), it still had to be adjusted. The cool thing about this bag is the compression bag that comes with it. Orlieb makes a similar bag with double straps for more security to the seat post.

Good for 6L

I've used it several times

I bought the 6L version, while it looks small I really enjoy it since it gives me plenty of space and more importantly gives me an idea of what really matters when it comes to extra shirts, it really keeps me in check , would have wished the outside was water proof so there’s no need for an inside waterproof bag add but it works, can’t complain since I got it on sale

Perfect for desert rambling

I've used it once or twice and have initial impressions

I used this on a bikepacking trip. I stuffed some extra layers and my jet boil in there. Has a ton of storage, but I didn't need it all and it rolled down nicely. Soild construction that should last for years to come. Strong mounting system to attach it to your seat.


Would this work with a carbon seatpost?


Interested in the 10L and 15L. What is the clearance I need on the seat post (I'm short!) Thank you
