Just wondering what air pump assembling an S&S coupled bike that will have completely flat tires from flying. Looking for something that will fit in an already crowed S&S case. Since space would be at a premium, I would imagine that this pump should be one that can mount on the bike so you can take it with you in case you get a flat while on the road.

Would a Topeak Morph or Lezyne Road drive pump be the best kind to get? I am thinking I should get one with a flexible hose to minimize the chance of me breaking a valve.

I have a Lezyne Gauge Drive HV on order for my travel bike with 26x2.0 tires. Also have the HP model for skinny tire bikes. Mounts neatly to the water bottle cage holes. Very high quality in a small package.

Alan, what is your opinion of the HP? I've been thinking about one becuase they have a pressure gauge. I assume you meant it was also a Lezyne floor drive pump. Any negatives?

Not the floor drive. This one.

Lezyne - Engineered Design - Products - Hand Pumps - High Volume - Gauge Drive HV

This is my 3rd Lezyne pump. Have the HP Road Drive and Gauge Drive HP already for other bikes. Repeat customer should say it all, but in case not, they are great pumps.

Right now our Surly LHT's are packed in my own cases. I fabricated them 3 years ago and they are ready for their 2nd. trip to Europe. I have the Topeak Mountain Morph in each case. Yep 2 pumps 1 for each bike!

brown, the Lezyne is impressively compact, which may be a real advantage for you. I have owned the bigger and less compact Topeak road morph for a number of years and have been and am still impressed with how well and quickly it gets a tire to 100psi. I very much like how the foot brace and folding handle allows you to pump with your arm force going into the ground, very efficient. The gauge on mine is fairly accurate, and teh build quality is very good, and the end that goes over the valve has worked perfectly well for the 4 or 5 years I've owned it.

if the higher price of the Lezyne is a factor, be assured that the Topeak is a very well made pump that functions very well.
Any pump with the flexible hose is nice to work with, after using standard frame pumps for years, its easier, faster and you do not have to be so careful of pump position while pumping for concern about the valve.

another factor, if your tires less much less than 100psi, then a smaller pump will work perfectly well, given how easily and relatively quickly it is getting to 100 or over using my topeak.

Several weeks ago I wrote up a comparison of the Toppeak Road Morph and Lezyne Floor Drive. At: https://www.bikeforums.net/touring/10...l#post18521373

I've been using Topeak Road Morph since I bought my S&S bike. Slim enough to fit easily into the case (although I put it in an old seatpost sack), and it fits securely on its mount when the bike is ready to ride. (Fortunately, I've only had to use it to fix a flat a few times out on the road!)

I've had the Topeak mini Morph for years. It's like the Road Morph, but shorter. So there's less air and less pressure per stroke. It's 10.2 inches long instead of 13.8 inches. And 170 grams instead of 200 grams.

Mini Morph test on 28c: (actually 25c in 25mm wide rims, measures 28mm and has the equivalent air volume. smaller tires would take the same effort, but perhaps few pump strokes.)
100 strokes -- barely rideable, still squishy, but could ride carefully on smoother roads. This pumped up quite fast to this point.
150 strokes -- at 60 psi. Rideable. Starting to push pretty hard with a my whole arm.
200 strokes -- at 75 psi. That's plenty for a front wheel, and I'd probably leave it at that for the back wheel too. Leaning hard into the pump. Takes effort!
No gauge is needed with this pump--I'll give up before it passes 90 psi.

I normally run these at 65-75 front, 80-90 rear.

Thanks, that's very informative and well written.

I use a Topeak Road Morph.

I have a Lezyne Road drive pump and it is well made and works pretty well. Can't compare it to the Topeak cuz I've not used one of those.

I still hate mini pumps, but the size is so convenient.

Just arrived. It's a bit wider than the HP models, but should be great for filling more voluminuous tires. Also, nice to have a gauge.

Another vote for the Road Morph. Love it, and and several of them. When traveling I usually pump up the tires as much as I can, and then try to find a bike shop on the first day and top off the tires with a "real" pump. But I can get the tires fully up to pressure with the Road Morph if I'm not feeling lazy.

Wow, excellent write-up! Nice job. This is well worth reading for anyone looking to make a purchase of one of these.
