Most Helpful Customer Reviews
I ordered two of these for use with the Vittoria Randonneur Pro II 37 RFX Fold Bike Tire. These have removable valve cores, which is at best a mixed blessing. I understand that in principle this is a good thing, at least for people who wish to inject sealant and such, but when the tires are assembled, the assumption should be that at least 80% of riders will never want to remove the cores. The cores should instead be factory-tightened to make sure they stay in. Unfortunately, this wasn't the case for either of the tubes I received.
I find these to be good quality tubes and have never experienced a manufacturing defect issue. I usually remove them from the box, put in a ziplock sandwich bag and sprinkle liberally with baby powder before storing in my seat bag for future use. The baby powder makes them easier to slip into place when installing and even easier to see if working in the dark.
We had two flats on one ride with these tubes the second happened because the valve snapped in two I'm never buying them again .
