I don't think the screw on chuck would present a problem with removable valve stems. It might mean that it is a 2 handed operation. It takes a little longer to screw in on as opposed to flipping a lever on other pumps, but you won't tear out a valve stem either which I have done with a Joe Blow Pro.

The CNC is completely machined including the piston. The alloy pump has is not built to the same tolerances but all of the internals are the same. When I bought my CNC, it was only about $10 more than the alloy version. I am very happy with my Lezyne CNC pump and I think it is the last floor pump I will ever need to buy.

How big is the lezyene head? What type of clearances are needed to use it.

I don't have any measurements but it is small and clearance shouldn't be a problem. The only issue I have had with it that there is a little bit of a learning curve. As I tighten the head onto the presta valve it usually tights the presta valve so that I can't put air in it. The solution is to open the valve all the way and press it to let a little air out of the tube. This solved the problem. I now do not have any problem getting air into the tube.

I got the Lezyne Alloy Drive for my birthday and love it! I considered the Joe Blow Pro, but heard a decent number of negative things about it.

my blackburn pump is okay. But I wouldn't say great but it was cheap so why not!

Same here. Been an excellent pump. Are there better? Yes... But there are a lot of crappy pumps out there.

another vote for the specialized air tool

I have a Lezyne CNC pump and love it. I can add one more negative review on the Joe Blow Pro. I have had a Joe Blow Pro for four years and every part on it has been changed at least once. The gauge was changed recently and the oring on the piston and smart head have been changed twice and now need it again. The Joe Blow is a disposable pump. The Lezyne is built to last.

Topeak Joe Blow Pro or Lezyne Alloy.
I already have the Topeak.
Getting the Lezyne next
(1 for work and 1 for home).

my Nashbar L'Orange has been awesome so far

Ok, so I read through the thread.
When I bought my Topeak Joe Blow Pro,
I had done a ton of research and it got great reviews.
The earlier models were troublesome, but the very first models worked great.
I would chalk it up to Topeak experimenting with cheaper materials to lower costs.
The latest generation Joe Blow Pros are great.

Mine has been completely trouble free and I use it every time before I ride.
It'll take me about 6 to 8 good pumps to go from about 80psi to 130psi.
It does what it's supposed to do without a complaint.

The only thing I'd change on it would be the handle.
It flexes at the ends a bit under my pumping.
I want a wooden handle the next time.

Truth be told, there was a time that I couldn't wait for my Topeak
to fail so I'd have an excuse to buy a Lezyne, but what the heck.
I'm going to buy one any way and as I wrote earlier,
use the Topeak at my jobsite for when I commute.

I was actually going to buy a cheap pump (under $20.) for a satellite pump (at jobsite),
but got to thinking that it wouldn't be worth the trouble and it was the perfect excuse to
go for the Lezyne.

:D

I'll get myself one for my birthday.

joe blow sport. had it for several years. no probs at all.

Topeak Joe Blow - Had it for over 10 years. I replaced its head with Topeak's upgrade kit two years ago. A friend has the Specialized Air Tool (mentioned above) which I envy since it takes comparatively fewer strokes.

that's interesting. i top up every weekend ride and it never takes much. a couple of strokes and i'm off.

+1 for Lezyne. I have an Alloy Floor Drive and a cage-mounted Pressure Drive, and I highly recommend both for all of the reasons mentioned above.

However, a word of caution - one of my favorite features is the screw-on chuck and I've found that if you're not careful/gentle when tightening it on the valve, after repeated use, it's possible to weaken and eventually tear the base of the valve stem from the tube. Of course, this is true for any pump with a screw-on chuck, and just something to be aware of while using one. Once I became aware of this and reduced the amount of torque I use, I haven't had any problems at all.

It's no big deal. The JB has been and still is a fine pump. But when the time comes, I'll consider an Air Tool or Lezyne (hadn't heard of that brand before reading this thread).

sometimes you need to see something in action. i have seen the lezyne mini pump in action when i helped someone on the side of the road and i was seriously impressed.

I just ordered the Lezyne Classic Floor Pump. Got it over the Steel as the steel has nylon threads on the fitting that attaches to the flippable aluminum valve head and thought the nylon could strip more easily with frequent flipping as I do for the variety of tires I have in the garage.

my budget is about $40..
so there are two options:

(1) http://www.amazon.com/Lezyne-Steel-F...=1X75QJNO2UXQN
(2) http://www.amazon.com/Blackburn-AirT...=1X75QJNO2UXQN

lazyne steel has good reviews.. but comes with 2year warranty.
blackburn comes with lifetime warranty.

lifetime warranty vs. steel made...
any opinion?

I've been using Serfas FP-200. It has been great so far.

+1 for Lezyne Alloy here

I just bought a Serfas FMP-500 on Amazon. Works well.

Lezyne hands down.

I may be the only person to have had a problem with a Lezyne. The gauge on the steel model broke after just a few uses. The screw on valve was a little fiddly, but once it's on, it's on. No popping off. The pump seemed to be a quality product. I took it back to REI for a refund but I may get another one.

I ordered a Topeak JoeBlow Turbo. It just came today and I have it sitting here waiting for it to warm up. Been sitting most of the day outside in -13 F temperatures.

I figured out Serfas FP-200 floor pump also comes with lifetime warranty.

my options are now :

(1) http://www.amazon.com/Lezyne-Steel-F...=1X75QJNO2UXQN
(2) http://www.amazon.com/Blackburn-AirT...=1X75QJNO2UXQN
(3) http://www.amazon.com/Serfas-FP-200-...=1X75QJNO2UXQN

Those are $40 range ones..
Lifetime warranty on pump...is it worth?

If it breaks they give you a new one...No questions, No problems.

from http://www.serfas.com/warranty.asp
"Serfas offers a limited lifetime warranty to the original purchaser of Serfas lights and pumps. This warranty only covers manufacturer’s defects and does not include normal wear and tear - including product that has been ran over, sat on, dropped off a cliff, lost or stolen."

"warranty only covers manufacturer’s defects and does not include normal wear and tear"

I'd better have a nicer pump (than a "limited" lifetime warranty or) with a limited lifetime warranty..
(Of course, it is always good to have lifetime warranty as an extra feature. :-) )

I had a cap on the bottom of the pump go missing inside my garage.
Went to the LBS to see if they might have a cap.

They handed me a new pump.

No Paper Work.

Wow!! what pump do you have?
