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.

I'm a pretty bad tire installer and these tubes survived two tire installs and lived. They must be pretty tough. Even better yet, they are flat black, so they match my new build even on the inside.
When I bought these, I also needed a steerer tube top cap and nut. Adam at TFB tossed me a free one. I'll be back for more bits.

Standard 29er tube. Feel light enough yet has that stout durable feel to them still. Worked great on the new build.
