Wasn't sure where to ask this but I figured people that frequent this section might be best suited. I do alot of group rides as well as commuting. I'm looking for suggestions on a good quality lightweight floor pump. I currently use an inexpensive park tool one that is always full of problems, mostly the head doesn't always switch over from Presta to Schrader and I end up having to bang it on the ground to make it work. I carry it in my messanger bag (just put it across the top of the bag and close the flap, both ends of the pump stick out of each end of the bag). Between the muliple group rides I could end up changing anywhere between 2-10 flats a week (for other people/sag support) also airing up tires before the rides so the pump gets alot of use. Looking for suggestions on a lightweight, good quality floor pump that's not to awkward to carry with my messanger bag.(I don't want c02 or frame pump)

This might fit your needs, I have one that I really like. It's not as fast as a floor pump, but much easier to carry.

Honestly, I would just get a good floor pump and carry a small pump with you in your bag. Cannondale is/just came out with one though that folds up fairly compactly. They call it the Airport Carry On (despite the title in the link below)

Although I wouldn't try taking it as carry on, because that sort of thing is limited to 7 inches for tools, and I could see the TSA not letting it through as carry on.

Just wondering why a floor model pump needs to be lightweight. I like my mid-range Joe Blow Pro for the garage and my mini-pump is also a mid-range Topeak. My tires are a mixture of Presta and Schraeder, and I like that neither pump cares. Just press the pump-head down on the valve, flip the locking tab, and pump.

I have not seen a floor pump I would consider light weight, at least as far as carrying on a bike. Typically floor pumps are meant for home/garage/shop use. There are several good small portable pumps designed to be carried in a bag or fitted to the frame as well as CO2 inflators.

I use a JoeBlow Sport II for my floor pump and have been for the past 2+ years without a hiccup using both valve types.

For my mini, I carry a Topeak Road Morph G. It still works, but the locking mechanism for the lever is stripped and the foldout foot support busted off. Will try out a Lezyne Drive or Pressure Drive next.

Why in the hell do you need to carry a floor pump with you?

That's really interesting, I wish I could find a picture that better showed it's size.

My dad bring a Topeak Road Morph (rated to 160psi I know it goes to at least 100psi from personal experience) with him on vacation and uses it to pump up his tires when he gets there when flying to another state. It's small enough to also be carried on the bike. Not sure if it's big enough to meet the OP's requirements though.

The Axiom HP Enforceair is rated at 200psi, not sure if it's a realistic improvement or if it's just marketing hype, but it's looked interesting to me:

The 2 pumps I just mentioned are small enough to carry on a bike frame so they'd work in a messenger bag. Topeak also makes a full size floor pump with the extra stuff on the sides folding to save space. But I bought one a while back, and it is a full size floor pump so probably to big for a messenger bag:

It's a little thinner and a little taller than a "regular" floor pump. I personally have no use for it, but I guess there is a market. One of the C-Dale dealers had a corporate rep from C-Dale come in maybe 2 months ago and he brought all of the new products they had out. It was pretty sturdy, but for my uses I would be happy with a Topeak Joe Blow(?)

We use the Pedro Prestige pump at the co-op. The thing I like most about it is it uses a dual head chuck, not an auto-sensing one. The schrader side does wear out over time, but new hoses are easy to come by. The Topeak JoeBlow Sport is similar, and some shops have the rebuild kit box to replace worn out gaskets and whatnot.

If the only problem with your current pump is the head, why not just buy a new hose? I like the attachment of lezyne pumps and my nashbar pump was ok but the plastic head was taking some abuse from metal threads, so I just bought a lezyne hose with their head and put it on in the place of my old hose. Sure it's still a crappy nashbar pump, but it was a cheap fix and it works a lot better with a better attachment now.

I liked how the Topeak JoeBlow Sport looked, and it's dual head as I figured it would work better than 1 head so I ordered one.
Nope. :-/
Had to send it back. Brand new pump was incredibly inconsistent in being able to attach to my presta valve.

I like a lot of the full size Topeak pump designs, but my one experience with their reliability was not great.

Floor pumps do work well because they let you push against the ground. But they are rather large to carry around.

Are You the Sag Wagon?

lezyne micro floor drive hpg? works well for me on the road, but I only go up to 100 or so psi. has a hose and a foot peg.

It's not uncommon for a bike tourist to take a floor pump along because, well, the bike is already loaded up anyway, so strapping a floor pump to the top of the panniers is not going to make a lot of difference.

I've had mixed results with Topeak products, they've got great customer support but that doesn't help you when you find out you've got a problem and have to deal with it now instead of after they've sent you replacement parts.

Maayybe some tourists do (still sounds dumb to me), but this is the commuting forum and the OP wasn't asking about touring.
