a pump question
 

I am setting up for a minimalist 9-12 trip in the spring, just a couple of stuff sacks and a credit card.

What pump can I use to keep my tires @ 100 psi that won't be the biggest thing I carry? CO2 the best option?

Mountain Morph G.............. it's big, but it works every time.

Probably the worst option for anything other than a quick inflate to get you through until the end of the day. Ever flat, fill with CO2 and then check your pressure a day or two or three later?


Road Morph G. It has a pressure guage, albeit one that can be somewhat difficult to read for those of us with failing eyes.

Road morph is easier to pump above about 75 psi than the Mountain morph IME. You can mount it on the left seatstay, where it doesn't take up any room. Best pump head I've seen, that little hose is a great way to push against the ground without worrying about tearing the stem out.

Road Morph G is one of the favorites on this forum, but make sure that the little knurled thingy on the chuck is threaded on tight enough to make sure it does not fall off. Toppeak told me that it was not covered under warranty, I had to buy a complete rebuild kit - and pay exorbitant shipping just to get another one. Next time I was in the store where I bought the pump, I looked at the three that were on the shelf for sale, two had loose knurled thingys and on the third pump it had already fallen off.

Lezyne Micro Floor Drive is another favorite on this forum, a little smaller, a little lighter, longer hose. Overall a very different design. The chuck threads on instead of the conventional chuck. If you get this pump, make sure that you either do not have removable Presta valve cores or if they are removable, tighten them on with a wrench before you use the pump. Otherwise the core can stay in the pump chuck with you unthread the chuck from the wheel.

I have both and like both. I usually carry the Lezyne in a pannier for touring where it is less likely to be stolen than on the frame.

My Mountain Morph G continuously pumps to 115-125, without issue, and does it faster.

Another + for the Road Morph. I wouldn't waste time with another pump for touring. It has a small inline gauge, a small foot pod and a nice hose so you won't be pumping directly on your presta valves. It might not be the smallest thing but small pumps are a pain to use and make getting to higher pressures even harder.

If you really can't imagine getting a well reviewed practical portable pump that is perfect for touring, then I would suggest one of the Race Rockets. They make a carbon version and they have a nice hose that extends and tucks away when not in use.

I have a Road Morph mounted on the downtube next to the water bottle cage, using the optional (bought it from Topeak) side mount. Is there a specific bracket to mount a Road Morph on the seatstay?

This is a pretty small frame-15" but 13.25 c-c-
fits fine-works great
no more hearing that Shhhhhhhhhhhhhh after several hundred too vigorous pumps with a small pure frame pump
Yeah the gauge is hard to read for 63 yo eyes-and it would be nice if it was higher volume-but it is quick enough

Check out the Lezyne Pressure Drive CFH. Mounts on the frame next to the water bottle. It's small, can handle high pressure, allows the use of CO2, and has a hose with a reversible Presta/Schrader chuck. I've been very happy with mine.

I do light touring exclusively, yet I carry floor pump with gauge. I carry plastic body light pump less than $20. I check my tyre's pressure every morning before my ride. I feel it's worth it's weight and trouble.

As happened to me one time. You take the tire off, change the tube, struggle to get the tire back on the tube without pinch flatting (this was a road bike with deep rims and a tight tire), pump the damn thing up to 100psi and psssssssssss. All the air goes out as you remove the pump and you feel like you're back (almost) at square one. Horrible.

I've used full stroke frame fit pumps on my many bike tours.

I don't think they have a seatstay specific mount but I imagine with some ingenuity you could take the original mount and zip tie it around (maybe use some shims if needed). I would get in touch with Topeak and see if they actually make a mount or have/will consider one. They are pretty big into modularity and I am sure they might consider it.

I have mine mounted on the seat tube because I have a ton of space between seat tube and my fender/rear wheel. I occasionally move the pump to my Cilo and that is done with a side mount as you have done.

Zip ties are your friend. At least when new, the mount on mine was flexible enough to bend around the trailing edge of my seatstay and tighten down with the included zip ties.

Topeak's mounts have changed over the years. This would be another reason to buy from an LBS, you can check the mount in the store (and don't buy if it don't fit).

CO2 will not stay in your tubes. It is only to get you to a situation where you can your can refill with air.

I bought the Road Morph G at my LBS and mounted the pump on down tube braze-ons. When I needed to mount the extra water bottle cage, I bought the side mount direct from Topeak online, since none of the LBS around here carried it. I do like the look of the pump on the seat stay - I think it would pick up less water and dirt when conditions are wet.

Topeak Masterblaster or Zefal HPX mounted under the TT or seat stay. I've used mini pumps like the Lezyne Alloy Drive, but after 2-3 flats, arms start cramping up from all the strokes. I'm a minimalist as well, but I don't skimp on pumps.

At 100 psi. the Road Morph would be the better choice.

I have used it to pump my 125PSI tires, and many other roadies to 115 without any problem whatsoever. Use it regularly on my 90PSI tires. Right now it rides on my Sirrus, and I pump them 115-125.

Another vote for Road Morph G - great pump! The hose and foot rest make it so much easier to use that a frame or mini pump, and since I pack a pair of reading glasses in my seat bag, my 62 year old eyes can read the gauge!
