Perfect for Enve 6.7's
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.

PROS: Good Stem Length

Great price, but issue with inflating.
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:/

Hold air well
It's a tube, the valve was straight, they look well made, they've been holding air like a proper tube should. The tubes I received were stamped as Kenda (on the tube, not on the box).
