I decided to get this pump despite that I already have the Topeak Road Morph. I need a second bottle cage for my century and it turns out that just to buy the side mount bracket for the Road Drive alone costs about $20, so I might as well get the pump/bracket kit. As a bonus, I might also drop the fred title from my bike.



Amazon is selling both M and L sizes. M is 8.5" long and L is 11.1". So I was wondering, if I went with the smaller size, will the pumping action still be fine and take a reasonably short time (assume a flat tube)? Or should I buy the larger pump? I'd like to hear from the users since it seems almost everyone here has one of these pumps.

Medium. Even the medium is almost too big.

giantdefy

Medium! Best hand pump, EVAR! Will not bend the valve like other mini pumps.

pdedes

i'll second the medium size. make sure you learn how it works before you take it out on your first ride. i hope you ditched the s/s bottle idea too. just sayin'.

Excelsius

Yeah, I'm getting 2 Polar Insulated bottles. That's the only brand using phthalate-free plastic and that will have to do for now until the technology for bikes catches up. Plus the reviews on insulation are really good.

I now have to decide whether to put the pump on the down or seat tube. Probably the latter.

My bike is white, but I think the silver pump will look fine.

Velo Gator

I have the white pump. It's quite nice.

And I'm not sure where you read that about the Polar bottles. In Florida they stay iced for about 30 seconds. But they're decent.

I'd gladly trade my medium for a large. Going to get another, large size, for my regular ride and move the other to the backup bike.

Nachoman

why do you prefer the large?

JoelS

Less pumps to get up to pressure. So it's quicker.

Excelsius

I was thinking that too, but you'd have to try both pumps to see if there is really any measurable difference in the number of pumps.

Does this pump have a gauge? I can't see any in the picture and without a gauge it would be pretty useless.

I was surprised by all the votes for the medium size above. Don't have a Lezyne, but have used them a little. Certainly with my Zefal HPx pumps there's a significant benefit in using the largest size that will physically fit on your bike frame. I have those in -2, -3, and -4 sizes and it takes a lot more pump strokes when using the HPx-2 as compared to the HPx-4. I'd expect a similar difference with the Lezyne pumps in different sizes. Given that the price is the same and the weight is only different by a few grams, why opt for the shorter pump if the longer one will fit on your frame?

Excelsius

Pictures?

The reviews on Polar are all over the internet, including Amazon, where it seems to be the most popular insulated bottle for sports/cycling.

Velo Gator

I'll snap one in the morning for you. Bike is in the car tonight and I'm lazy.

Excelsius

If the difference in the number of pumps is large, then I don't know the reason for going with the smaller pump either. The large one will fit fine on my frame. In fact, my Road Morph is only about an inch longer than the large Lezyne, but many people said that's "fredly." I'm mainly getting the Lezyne for the side mounting frame bracket so I can mount the pump underneath my second bottle cage.

Velo Gator

Found one on my phone.

DRietz

You need a gauge to know when a tire is at a decent pressure?

I'm sorry, but really. The tire generally needs to be almost hard with the press of a thumb.

Ritterview

Still having a frame pump won't help you there.

Instead, get a 60 gram 99 mm Airbone Supernova Pocket Bicycle Pump, which will fit out of sight in your saddle bag. With some effort it will get your pressure up to 70 psi.




Then carry a 5 gram Lezyne Speed Drive CO2 inflator.



And carry one smaller size (40 gram) 12 gram CO2 cartridge, which will get you up to 120 psi.

If you have one flat, the combo of pump and CO2 works well together, and gets you to 120 psi. If you have a second flat, the pump will get you to 70 psi, which will get you going until you can find another pump or CO2.

I have the smallest Lezyne pump that I've had on the bike for a couple of years. Until yesterday, I'd only used it to put a bit of air in the empty tube to give it some shape. Yesterday I had a CO2 cartridge launch itself across the parking lot, so i had to pump the tire up entirely with the Lezyne. It was surprisingly easy. I got plenty of air into the tire, and it didn't take an excessive amount of time. On the last few pumps it was kind of hard finding some leverage so I could bear down, but it was fine. I don't think I would bother with the M or L size. The small one worked fine for me.

Recently got the M and am wishing for a L instead. Looks almost comical in size while mounted along the downtube

I think a longer stroke is almost more comfortable and short stabbing jabs

Excelsius

That would mean that a large number of members here are freds! Hahaha.

Ok, I got the large one. I think that there is no good reason to get the smaller one, especially if that will mean that I will have to hold up an entire group for a longer period just to replace a tube. Not too happy about the absence of the gauge, but given that for over 500 miles I have had no flats, it might be ok to ride with an approximate pressure once in a while.

Will post pictures once the setup is ready.

Warning: PG 13 material follows:

Medium works well for me. I have used it on a number of flats and pumped to over 100 psi easily and with no issues. Though it does take more strokes, I doubt it takes more than a minute longer than using the longer pump. A lot depends on technique. There are a number of ways to position yourself and stroke the pump. The one I like the least is to position the tire in front of me with the pump pointed away and pushing to stroke. Better is to kneel on my right knee with the wheel leaning against my left knee. The pump passes through the spokes supported by my left hand behind the wheel against my thigh and I stroke with the right hand pulling toward my thigh instead of pushing. A second method which also works well for me is to sit with the wheel in my lap, support the pump head with my left hand supported on top of and supported by the wheel and stroke like I'm...uh...pleasuring myself. Practice makes perfect...

I have the medium. It works fine for me.

For people asking about a gauge, it doesn't come with one. Lezyne does sell a hose with a gauge separately that you can use in place of the stock hose.

You look forward to getting flats, don't you?

I have the micro floor drive. Not the fastest pump, but it does the job and looks nice on the bike.
The micro has a little "foot" you can fold out. I find the corner of a spd road cleat will fit nicely to hold it down while you pump.
