The tube is heavy, not just be...cause of the filling. The presta valve is good quality. I hope it will seal against small punctures in the tube. I also bought tire liners.

Theese tubes are a real lifesaver. I ride my bike every ...day and numerous times I would have ended up walking back home had I not invested in them. I have been using them for a few years and I wouldn't go riding without them now. They cost a bit more but well worth the price...they will give you peace of mind that comes with knowing you won't be getting a flat while using this product. I am very satisfied and would reccommend these tubes to anybody that rides a bicycle.

Have a couple of MTB tires that are not tubeless ready and this tub...e has made them usable and reliable. I am impressed with how well it seals and how light it is.
