Flat Repair Air

If you ride tubulars, do you carry a pump, co2, both, or neither? And, why?

It's been many years but I used a pump. Now I'd use CO2. Two cartridges, just in case. And obviously the spare tire.

both, because I've had issues w/ both. I'm also a devoted Schrader valve user because I've had issues w/ Presta valves. so if I get a flat near a gas station, I have 3 options for air. love the redundancy

They make tubular tires with Schrader valves? I didn't know that.

I use a Topeak Roadie TT mini Twin Turbo pump. No gauge, and presta only, but two-stage and double action.


modern sew-up pump

The short strokes are easy and surprisingly effective. No problem reaching sew-up pressures. Not for fat bikes...

Pump only for me.
If I'm fixing a flat out on the road, there's a good chance I'll miss whatever caused the flat, despite my best efforts and flat again. If I had only CO2, I'd be out of luck.
The ultra compact pumps put out by Lezyne are SO compact, they snuggle right in next to the bottle cage, and I think they're actually lighter than a CO2 inflator with cartridge as well.

Can you spot the pump on the far side of the seat tube, next to the bottle cage? (sorry, I don't have any left side views of this bike since I added the pump)

Forget what I said about Schrader valves I overlooked the OP mentioning tubular tires but now I’m curious why They added that specification to asking about how people inflate their tires. forgive my ignorance, what is unique about tubular tires that affects how you inflate them?

^^^ I wondered that as well. All I can figure is he might be interested in carrying only CO2 since there is no need or opportunity to fix multiple flats.

My only guess is that it's a different dynamic since generally, once you get a puncture, tubulars are considered out of commission until you get home and repair them. I never ran tubulars except at races, but if I were to ride them daily I'd probably have 1 spare tire, 1 CO2 cartridge, and 1 tube of glue or tape... and hope for no more than 1 flat.

My reason for asking is I am trying to decide, for long rides in the SC summer, whether to put my Topeak Mini Morph on my bike or use those attachment points for an extra water bottle and just carry CO2 in my bag. I wondered what other folks did.

On one of our C&V rides, one rider got a puncture in one of his tubulars. I can't remember whether he added sealant to the tire then, or already had it in the tire, but it sealed and he re-inflated it with CO2, and rode the remaining 20 miles of the ride without a problem.

So now, on the exceedingly rare occasions when I ride with tubulars, I carry sealant, a valve core wrench, and a pump. And a spare tire.

And a phone.

Is it the cold, perhaps making the plastic fragile?

I simply use Zephal HP or HPX pumps because they work. Failures are so rare I feel zero need to carry anything else. (Last failure was on a group ride when I lent it to someone after I tired of pumping other's flats. My tires did fine but we had flats well into double digits on the very rough "gravel". Those Zephals have bailed out many others over the years. Silcas, CO2, minis, nothing.

Also, pumping isn't hard. Can top off to any pressure. A skinny 40 yo engineer type pumped both tires from dead flat to 120 psi for a TT using my HP in my racing days.

That has been noted else where, for the Rene Herse is that they specifically recommend slow inflation in 15 lb increments due to the way TPU stretches, so being conservative, no co2 and only shop floor pump not compressor for TPU tubes

I bought a pump bracket that fits on the side so I could carry my Road Morph and a water bottle. Looks like it's still available on Amazon: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

I also bought some velcro fasteners to make sure the pump stayed in the bracket when I rode.

For my other bike, I bought a rechargeable electronic pump. https://www.amazon.com/gp/product/B0...e?ie=UTF8&th=1

Hope you don't have to use either of these on a ride! :-)

You must live near Greenville and ride with the pros. Otherwise, how the heck did you end up riding tubulars?

That CO2 is going to leak out of the latex inner tube of the tubular tire pretty quickly, and most tubular tires use latex Tubes.
The other issue is- if you either use sealant inside your tubular or use sealant as a fix after puncture- that CO2 is also incompatible with the tire sealant.

I had to change a tubular on a long ride out in the Everglades. Presta valves and canister adapters can be tricky at times, I lost most of the gas from the first canister, and much of it from the second, and got my tire filled only enough to keep the rim from bouncing on the ground when going over bumps. Now I carry a pump.

As the OP I would like to explain why some of you are so confused by my question. There is an important point of which you are unaware. That point is, quite simply, that I am a moron. I had a brain fart and said tubulars but what I meant was clinchers. Sorry.

Well you had us going, for sure! Kudos for 'fessing up. There was a newb in "Road" recently who actually didn't know the difference but went through much dissembling rather than admit it. Now that we are all aboard, I'd figure a way to carry both pump and an extra bottle or two. It's not too annoying to carry a pump or an extra bottle in a jersey pocket. I also use the pump brackets that piggyback on the cage mounts.
