TeravailStandard Presta Tube - 700x28-35C, 40mm
4.3
Q-tubes are great reliable replacement tubes that come in a variety of sizes for most applications from the smallest kids bike to world class race bikes.
- Presta valve tube have an external thread and are thinner that standard Schrader valve tubes. An adaptor can be fitted onto this external thread to permit the Presta valve to be connected to a pump with a Schrader head.
- If you are going to use Presta tubes in a rim that is designed for Schrader tubes you must use an adapter such as the Wheels Manufacturing Presta Saver to prevent damage to the valve stem.
- Presta tubes work better in high pressure tires because the valve has no return spring which pushes the valve closed under pressure. You close the valve by turning the valve core shut.

Perfectly fine tubes. I'd get ones with longer stems next time though. 32mm is short if your rims have any depth to them.

I've used these tubes several times and they work just fine. They're some of the cheapest I've found and they're a bit heavy... but reliable.

These seem perfectly fine, no issues with them over about 2000 miles. No flats so far, but used them with mostly Vittoria Rando II's on my Vaya. The tubes also came with more powder than many other tubes I've tried. The weight isn't a issue, they are thin, but without being risky like the lighter stuff. Had bad luck with the seams on many others out there, and there isn't good tubeless touring tires available in 700x32 that run at higher pressures and roll well.

I like the retention nut on the stem. It holds the tube in the proper position while the tire is being installed. The stem was a little longer than I needed but that was not an issue.
