Are the rear tires on a B2650 tubeless from the factory? I have a leaking valve stem and I was curious whether I just needed to pick up a valve stem or a whole tube.
Bingo, again.Or perhaps you are simply unwilling to accept cost savings as a manufacturer's reason for eliminating a part that is perceived by them as being unnecessary?
Enjoy your tire tubes. Just like tubeless tires, there are valid reasons to use them.
One advantage you gave up is the ability to use tire plugs on small leaks.
