I use 60mm deep CF rims and with stem extenders for the original 40mm valve stems. Having to lock the Presta valve open and then fitting an extender often meant that the valve wouldn't seal a low pressure for fitting the tube. The 80mm. Presta valve stem has solved the problem, no more pinched tubes. The tube is super light and so far no punctures after a 100 miles. The one piece tube also makes it easier to store a spare in my saddle pack. Highly recommended.

You would think so, but not all inner tubes are created equal. So far, the brand that has lasted has been Continental. These are super light and did not blow like the others. Stay away from latex inner tubes; especially the Challenge brand; both blew after mounting. Trying some continental tires now as well and they are super so far.

Smooth stem looks good. The only downfall is that it is not black for carbon wheels.

Great light tube. Removable valve in 80mm stem a big plus.

No threads on the valve, so I can't put a nut on it to hold it in place to put air in it. Another learning experience.
