Works butylfully.

The Continental Race Light Tube is the company’s lightest non-latex offering, making it ideal for those of us who compete in longer races, or who would rather not pump up our tires every few days. If you’re running high-end race tires on lightweight wheels, the Continental Race Light Tube completes the trifecta.

  • Butyl rubber
  • Removable valve core
  • 42 or 60mm valve stems

These are a staple in my saddle bag -- light, effective and necessary. The 42mm will fit most rim depths.


great back up tube

  • Familiarity:I've used it several times

bought as a back up tube, but ive been running with one for a few months now. holds the air great, and have not had any issues with them. I also carry one as a back up, and it takes up no room, and is super light, i cant even tell its in there.

Do these tubes have a removable valve...

Do these tubes have a removable valve core?


Yes, these tubes do have a removable valve core.

Great News!

Note: These tubes feature removable valve cores. Great for adding slime or stem extensions.

On some websites cyclists are complaining that when using a screw on pump the removable valve core shoots off the stem when they unscrew the pump. That's because when installing the tube (fresh out of the box) the removable core is factory installed only finger tight. You will need a 4.5 mm metric wrench (or presta valve core tool) to tighten the core for the first time. This will allow for your plastic valve cap, or your screw on pump to be taken off your stem without the core flying off.

NOTE: When tightening the core in the stem, hold the stem firmly and be careful not to twist or damage the stem base connection to the tube.

Ride Safe . . Have Fun


Mmmmm, Bit disappointed

  • Familiarity:I've used it several times

The tubes run well in the tire, but I have to admit, that they have been a little fragile when changing them out. Ive ripped a couple when doing so, and that very well might be how Im changing the tubes out, but I have never had that problem before and Ive change many tubes BUT.... they do run well for a clincher wheel


New tubes

  • Familiarity:I've used it several times

While replacing my tires figured I'd swap the tubes as well. Lighter than what I was using before. Like the yellow caps too

New tubes

Great tubes

    These are a bit lighter than some other brands, though probably not by a huge margin. They do have removable valve cores, which is not that common. You can use a sealant like Stans in tubes too. Your tire may still flat, but you might only have to re-inflate rather than replace the tube. I have also bent the little core stem on other tubes and had to replace the whole tube. Could have just replace the core on these. I find they hold pressure pretty well, maybe a loss of 10psi or so over a few days. You should check your tire pressure before every ride anyway.

    I don't understand why removable valve core is not an automatically listed attribute. Also the only types you can use with valve extenders
