Review on ๐Ÿ”’ Stans No Tubes 40mm Presta Valve Extenders with Threaded Design by Daryl Fitch

Revainrating 5 out of 5

For tubulars or tubes with DETACHABLE valve cores

Much better than valve extenders that fit over existing valves and use a friction fit to open and close the valve. Just make sure you have spare valve cores on hand in case the existing valve core becomes damaged or lost in the rebuild. Also, make sure your tube or tubular tire has a removable core, otherwise it will be completely useless.

Pros
  • CNC machined aluminum valve extender, 2 grams each
Cons
  • Hard to tell
