I like the pump. The bracket that attaches to the downtube is made for a cylindrical downtube. I had to attach the bracket upside down to fit it, I could still attach a bottle cage over the top of it which is good, but the down side is getting the pump out of the Velcro straps is a pain due to the upside down mount. Just a heads up.

(6 month review.) This worked great for my fat tire bike, refilling the tires quickly/easily enough that you could use it as a primary/home pump, but also small enough to use as a travel pump. Happy with this purchase!

Gotta say this mini pump is impressive. Really puts out a lot of air. Have had no problem filling beach cruiser (tubes), gravel bike (tubeless) or MTB (tubeless) tires. But it does come at a cost - it is bulky for a frame mount - almost double the diameter of my other mini-pumps. I carry it in the fame bag on my gravel bike so it's not a big issue for me. I think the trade-off is worth it. It is a very small inconvenience to switch the internals to change between schrader and presta configurations. My tubeless tires are all presta and that is what I bought it for - really tried it on the beach cruiser (schrader) just to test if the pumping power was as good (it was) - so I probably won't change it much, if ever. But there are some pumps that are slightly easier if you do need to switch between both frequently. Since a mini pump should really be for emergency use, I would still choose this pump because of how easily it inflates bigger tires over the minor inconvenience of swapping internals.

The pump itself works great. I can pump up my MTB and fat bike tires in a reasonable amount of time with it. I’ve broken 2 of the plastic mounting brackets when they were bumped by things in my garage. I’d like to find some metal brackets that won’t break.

Small but it puts out the psi. Still new to inflating the tubeless tires. This pump is awesome. Fits in your bag or on your bike.

This is a good quality mini pump. Overall feels solid from end to end with the gauge is clear and legible. The side lock keeps it secure while you pump the air.One day, I had a flat on the way home. Luckily,it was a small pinch of hole on the tube. I was able to patch it, using this mini pump the tire and back and running in 10 minutes.However, the only down side is 60psi max for the gauge version. If you don't need anything more than 60 psi, this is a great mini pump to have. I highly recommend it.

I have a 29 er mountain bike with wide 2.4 inch tires. I immediately researched and bought this after using a road mini pump to attempt to pump up a single tire 100 pumps later I had barely reached 20 lbs. With this pump I got to 30 lbs with 50 pumps. Certainly not as good as a floor pump but I am delighted to carry this high volume mini. Please note if you are using the smaller Presta valve you need to unscrew the end cap and reverse not only rubber grommet but also reverse the plastic valve underneath the grommet. I only gave it 4 stars because it is harder to pump than a floor pump but so much easier than a road mini pump. And 4stars for weight because it is heavier than a road mini pump. The increased weight makes no difference to me.
