One tiny little problem with Enve 6.7's is if there is any play with the stem itself it will cause an annoying banging sound hence the need for a threaded stem with lock screw. The 80mm stem is a perfect fit for 70-60mm carbon's. I put a very small dab of thread locker on them and a few ounces of Slime in the tube and my wheels are both silent and bomb proof.

I was using these tubes almost exclusively for several years but noticed two consistent problems:

1. When inflating them with my Blackburn floor pump, I'd have to attach the pump at least 3 or 4 times before getting a good seal. I'd get it attached, start pumping and hear it leaking out from around the stem. Sometimes I couldn't get it to seal at all on its own and had to hold pressure above the valve stem with one hand (or a foot) while trying to somehow pump with the other. It wasn't until I tried other brands of tubes that I realized the problem was with Q-Tubes, not the pump.

2. The other problem occurred a couple of times out on the road with my Topeak RaceRocket pump. When unscrewing the pump head after inflation, it would also inadvertently unscrew the the removable valve core. Admittedly this is partially the fault of the pump, however it led to much cursing and the decision to buy tubes without removable valve cores.

Since switching to Michelin tubes with non-removable cores, both problems have been solved.

FWIW most of the 'Q-Tubes' I received were actually manufactured by Kenda.

    use the removable presta valve to put Stan's No Tubes in to lessen flats from goat heads and small punctures in general works pretty well

          May have been a fluke, but I literally installed the tube, inflated it, rode to work, and when I returned to my bike after work the tire was completely flat. I pumped the tire back up for the 3 mile commute home, and by time I made it home, the tire was nearly flat again.

              I've been using these tubes on my fixed gear bike for awhile now and I havent had many issues other than a few flats. Part of that was my fault as I was using a size too low as far as the tube stretching and becoming thin. Once someone at jenson told me to try the next size up (23-25) I havent had any flats since so just be careful and make sure your tube matches the tires you're using

                I only use tubes with removable cores as I always put a couple oz of Stan's in them. These work as good as Continental tubs but are much cheeper.

                    I bought this tube for my brothers fixie bike. He's only ridden the bike a couple times since installing the new tube, so we don't know yet how well it'll keep from being punctured. Did have an issue with the bulging out of the tire I when inflating. Specifically by the stem area:/

                        Just regular tubes that do the job. All have been good out of the box with no defects that would make them non-functioning. The valve cores are removable, so make sure the core is tight so that it doesn't blow out.
