Lezyne

Bought this primarily for tubeless set up and it works great! It will only thread onto a valve core, so for tubeless just remove the valve core and hold the head onto the valve stem, flip the switch, and it will seat first try. I did four tubeless tires within 10 minutes without any issues. Because you do need to build pressure in the chamber before using it as a regular pump, I still use a different cheap floor pump for regularly topping tires up. Though it only takes a few extra pumps if you want to use this as a "normal" pump too.

I�ve now bought 3 of these for all the bikes�. The CO2 inflator is worth the price of admission alone, and not having to carry a bulkier, poorer performing, more expensive inflator is just awesome. It�s not the lightest, but considering that you�d likely be carrying a more minimal multi tool and inflator, it�s a wash unless you don�t need a chain tool, spoke wrench or rotor truing tool, which may be surplus for most days and unnecessary, until they aren�t. The quick link magnet is also just a brilliant addition that goes unnoticed until you need it.

I use it for a velomobile ( a recumbent bike that uses a monoque carbon fiber frame). I bought this because of the inline gauge but it's pretty small and hard to read at the angle I have to fill it at which is difficult but it still gets the job done. I bought also because of the elbow it comes with that makes it easier to get to the valve which is difficult to do because of the body being so low that makes it difficult to fill and see the gauge but is the best one I found and was as good as the Topeak. Road Morph w/gauge. I still like it and it is better than most mini pumps I have tried and because it does't have a lever to secure it in place that gives me more room to maneuver the head around more from different angles, you just push it on and that's it. It pops off once in a while at higher pressures but I am able to hold it in place most of the time.

Great multi tool. It's a little heavy, but when you consider you have a chain breaker, rotor truing fork and co2 nozzle on top of all the normal/needed hex, T* and driver heads, the weight is actually pretty minimal if you need or like to have those tools with you on a ride.

It's no heavier (that I can tell) than the crank bros multi tools, and those have been pretty hit and miss for me on my two that I have (one spindle on one just broke when tightening up my axle).

I like these Lezyne tools so much that I'm slowly replacing my multis on my other bikes with these.
