Lezyne

CNC Drive Floor Pump

Looks great but severely annoying

Familiarity:

I've put it through the wringer

See the other reviews about how the convoluted head removes valve stems. I finally pulled the head off this and stuck a Silca chuck and hose adapter on this for just $60 more and now it works well. Obviously you should get a Silca Pista and skip the extra steps.

Great tool to remove valve stems

This isn't easy to thread on, and when it does it often removes the valve stem when you take it off. I've had it too long to return so I'm just going back to flip type pumps. It is a total waste of money

Terrible Pump

Familiarity:

I've put it through the wringer

I've been using this pump for almost a year now. It works about 50% of the time. It is so frustrating to buy a higher end pump and have it cause more problems then solutions. The last time I used it the presta valve came off my bike. This is not a user friendly pump. I don't recommend it if you want an easy to use off the shelf product. I have three bikes and ride almost everyday, so I am not a "once in a while" rider.

Great valve core remover... bad pump

Familiarity:

I've used it several times

First off... don't buy this pump, there are way to many other good options. The only problem (and it's a big one) is the head. When the pump works.. it works great. But, it can be difficult to attach if you're in a hurry or your valve is a little grimy. Once it is attached, there is always this first pump where the gauge goes way up, then it feels like a seal breaks and the air equalizes between tire and pump... I've learned to live with that. What I can't live with is that if your valve cores are not tightened down with pliers, this pump with remove your core EVERY TIME. There is nothing more frustrating than when you think you're about to jump on the trail and then all the air comes rushing out of your tube or tire. The only reason I didn't throw this pump off a bridge out of anger is that I never lost a bead the few times this happened. It's just a bad design on an expensive pump which is inexcusable. I don't know why I keep buying Lezyne products. They suck.... I think they make stuff for people who don't really ride bikes or work on them, and just think they are trendy.
