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.
When I started taking my 7 year old grandson out in his neighborhood I noticed how many people might back out of their driveway and see him at the last second. There are no sidewalks in the neighborhood so we don't have that option. These lights dramatically improve his visibility to motorists and walkers. They are easy to charge and would also be fine on your road bike for casual commuting. I want something a lot brighter for early morning , winter gloom or twilight rides All of the Lezyne products I have bought have met or exceeded expections.
Lezyne never disappoints. There is a learning curve as instructions are not the best, but youtube videos help you understand how to set the tubless tire before adding sealant. Tip, remove valve core, of course, from wheel valve, after installing tubeless tire. Then you cannot 'screw' on the head valve, although it seems odd, you simply hold the pump to the open core until the tire 'pops' adubily into place. then, add sealant at a 45 degree angle of the wheel, so that the sealant can flow down the interior of the tire, replace valve core, inflate, and you are done! Super simple. And as a daily pump it is nice and the inflation gauge is at the top, vs at the floor like so many, so easy to read. Great quality product, cannot go wrong if you do not have an air compressor and do not wish to waste CO2 cartridges for setting tubeless tires at home.
My floor pump came with the old head, which was always iffy from the get go, but just suddenly stopped sealing one day after frankly not that much use. This one ... at least it's not a guessing game of did I get it on right, but the first tube I tried it on, it doesn't work with. For some reason. All my other tube stems work great, but the one on my rear trainer tire, it's like it doesn't screw down quite far enough or something and the stem valve never opens. Oh well. At least it works most of the time.
