Review on 🔧 Schwalbe SV15 700C Inner Tube: Ensuring Optimum Performance and Quality by Peter Bates

I am very happy with these pipes. Their quality was even more evident when I had my first puncture (with over 3,000 miles). When you inflate the tube to find a leak, it maintains a permanently round shape, unlike most tubes that bulge out in random places, like a snake that has eaten but not yet digested. They also have replaceable valve stems that allow you to add sealant or replace the stem if the end of the stem snaps off (I've thrown away some good hoses because of broken stem ends).
