安定の製品。不満なし。最近２５Cが主流になりつつあるので、ちとこれから買うのは微妙かも。

I bought these to use with my new wheelset, Baixiang 700c 60mm Carbon Clincher for Shimano. The presta valve is too short, it is 62mm from the base to the top of the valve, however, the body of the presta valve is what really counts and it is 55mm. I tried to use an external valve extender, but you can't lock the valve open due to its mechanics, so you have to fill up the tire with the extender, remove the extender and lock the valve (it sticks around 5mm out). You better carry the extender with you. Forget about the internal valve extender, you can not remove the valve core.I also damaged one of the tubes while trying to mount the tire and it was very easy! The rubber is really thin (they managed to make it light weight by using thinner rubber, cheap valve mechanics and no threads to lock the base).I weighted the tube, it is 75g, I compared to a Specialized with similar dimensions (107g).
