Which under seat bag do you use?

I have fit this under seat container to all of my bikes:


It is made in Australia, and the maker ships worldwide. I just can't stand the cheap hanging bags, this fits so sleek.

Thx JStrubeI. I like the way that model becomes part of the bike and "clamps" onto the seat rails. That one looks ideal for dropper posts. For me though, it does not look like it has enough room.

It isn't really large, they do have a large "clam" though, and with the "lunch box" on my Canyon MTB, works pretty nicely. I can carry a tube, some levers, and my multi tool. I have the smaller one on my gravel bike, and carry a tube, levers, and C02. I have a "Stomp Pump" on my MTB, so don't carry any CO2.

I always wear my water bladder riding my mountain bike, so I have some room left over in there for anything extra, which is usually just another tube. I have the Henty pack, so it sits on my hips, not my back.

What are you carrying that I need to add to my kit? :)

Thx JStrube, Post #424 above shows the bag I finally settled for. The extra stuff over and above what you have doesn't take up much room, but what I've crammed into this bag doesn't leave much room for even "air" 😜: My kit: Tube, 2 CO2, patches, 2 levers, inflater head, multi tool, extra chain link, valve tool, boot patch, 3 small cable ties, 2 band aides.

I also went with an Osprey lumbar bag which I carry a real light weight tire pump, I don't trust CO2 as if I can't seat the bead I'm screwed without a manual pump. I might need the CO2 for the quick blast of air (without the valve core) to seat a tubeless in the near future (first flat and I'm going tubeless) and I can be 15 miles from my car or house, wallet, regular glasses and a few other personal items like Clif bars. As it gets colder I can also carry some warmer clothes like bike jacket, head band, gloves etc too. Holds two water bottles also. I only use one of the tuck away bottle sleeves as I have another water bottle holder on the down tube. So far after several rides I don't even know this lumbar bag is on my low back 👍🏻.. I currently own 2 ebikes so I can swap the bag on the Trek now to the Giant.

My LBS last month when the bike was new tried to mount my tires tubeless as the rims are tubeless ready, but they were oozing Mucoff as the shop did not realize these Trek OEM tires "were not" tubeless ready. So they put the tubes back in. When these tires wear out (I can wait because I like the tread pattern) I'll buy tubeless tires. Then I might look into the bag you have in their larger size as I might need a tad more room. I'm not going back to carrying my emergency kit in a backpack or lumbar pack again as the kit is heavy! It's great transferring that weight to the under the seat bag and forgetting about it.

Nice little list!

Check out the "Stomp Pump", I love mine.

It sure is better than those jerk-off type hand pumps. The guide on our Bend, OR trip was pretty amazed when I broke it out, vs, having to use his pump.

I've never heard of your Stomp Pump. Those hand pumps don't push enough volume to seat wider tires especially tubeless tires anyway, hence the need for CO2's. With the valve out, one can push a little more volume. That pump because you stomp on it may push more volume.

I bought it at Sea Otter Classic a few years ago. They were there last year as well. It is really an upgrade over a hand pump. I haven't carried CO2 on my MTB, just my road bike. Usually, if I have a full flat on the MTB, where I pull the tire off, I'm swapping a tube in, I'll seat it at home with the compressor tubeless. You use the really big cans of Co2 for the MTB I reckon...
I always buy some nifty products at Sea Otter as many companies debut them there. Always something nifty.
