I had two Ritchey aluminum rims that had somewhat failed at the inside of the valve holes. Possibly due to me over-tightening them. These valves have a large rectangular base that covered the failures and with some extra Stans Rim Tape allowed me to keep using them. All valves should use this large rectangular base design versus the round valve bases. Yay!
I like the part that goes in the center channel. My previous tubeless stems have rubber cones that could rotate easily, and once that happened, it's hard to fix without taking things apart. It also comes with a nice little cap to remove the valve core.
