Why does the valve on the 60mm 700x25/35 only measure 45mm?
I have a set of 50mm carbon wheels I've been using on the road, I bought the Conti 60mm 700x18-25 Race 28 tubes and used them without issue. Now I'm moving the wheels to CX, I bought the 60mm 700x25-35 Cross 28 tubes, the problem is, the valves only measure to ~45mm. They clearly do NOT work with the wheels. Why are they advertised as 60mm, when they're only 45mm? The 18/25 60mm tubes measure out to a true 60mm. Please advise.
