Review on 🚲 Continental MTB Bicycle Tubes - 26, 27.5, 28, 29 (1.75-2.25) with Presta Valve 42mm - Value Bundle of 5 Bike Tubes by Anthony Savage

I bought these for a removable valve core so they can be used with Stans Sealant. So one star for the swap core. The reliability of the pipes is only average. What's not just average are the FUNNY long valve stems - actually 2 inches protruding from the rim. I've seen a description that says 42mm but it all depends on how it's measured as to what you can actually get. What I received was a SCREW BARREL. Incredibly long, making them prone to breaking while riding. Continental, why be so stupid? Gave them back. look elsewhere
