I've noticed those "new" RideNows with the allow stems, but avoided them because why mess with success? My limited experience with tpu tubes was that if the tube was going to have an issue it would be an issue with the valve or the bonding around the valve. But, if you guys say it seems improved, then I guess my next lot will be of the "new" style.
I guess RideNow seems to have their act together a little more than some of the others, I've noticed. If they say it's an improvement, I guess you gotta trust them.
