It's a quality pump. Reading the other reviews, I had a similar issue, where it just wouldn't release air fast enough to seat the tires. Then I removed the valve cores and it was perfect. Maybe if you had higher flow cores, you wouldn't need to remove them first. My process is to remove the core, seat the tire. Fill it with air. Then deflate it, add the sealant, the valve core, and then re-inflate. This works perfectly in those steps. I think it is a bit expensive, but you don't need to bring an air compressor to the trails with you.
This is quite easy to use, and works well for my presta valve on the 23s I ride on. I haven't had any issues with the valve connector. Many of these pumps are small and require a lot of work and repetitions to pump the tire up to even a small amount of air, but this is larger, about an inch in diameter and about 9 inches long, and really is pretty quick, at least enough to get you home.
Of course, the downside is that it's a little harder to sneak it away in a small bag attached to your bike, or always have it in your backpack, but I think it's worth that inconvenience.
This would be excellent for bike packing just because it would be your primary pump.
I wish it had another way to attach to the to the bike. It has a clip for attaching to a water bottle cage, which looks great, but I think it only works for the seat tube spot, and not if you already have a water bottle cage on it, and my bike has only the one on the down tube anyways. It's hard to find a way to attach it otherwise, but I think that's more of a me problem.
I bought the medium Grid bag. It is a very sturdy and well constructed bag, but slimmer than I expected. Also, if you plan to hang a Garmin Varia off the back light strap, it will sag and aim pretty much down. You really need to be creative to fit much into the bag. I had to get a TPU tube and a smaller multi-tool, rearrange stuff a bit, but now have enough room for 700c TPU tube, multitool(with tubeless plugger), CO2 inflator, tire lever and Tyre Glider tool, and thin rubber gloves and paper towel . Anything more would require the large bag. It really locks into place under the seat. Varia needs to mount on the bike seat tube though, instead of the back of the bag.
I installed this on my mountain bike, an older hard-tail, and after some strap swapping it fit better than I had expected. I made a cardboard mock-up using their dimensions so I knew it would be close. I have cables under the top tube and was concerned that they might not work well going through the straps, but it hasn't been a problem. I've put a couple hundred miles on the bike and the frame pack has stayed put and performed well. I like the flexibility to shrink the pack if I want to, but so far it's stayed at the maximum size, and the movable divider really helps keep things organized. I carry an extra water bottle and snacks/lunch in the main pouch, and some things I might want when I first get to camp. It's convenient to get to without having to dismount and retrieve stuff from the panniers. I really haven't had a Blackburn product disappoint !
