I was really skeptical about getting rid of my tubes but I got an opportunity to ride on borrowed tubeless rims for a month or so and I really like them and I’m converting my newest wheelset to tubeless using Stan’s.
I like the fact that with the tubeless you can always take out the valve stem in the field and put in a tube if necessary. I’ve been running the Stan’s fluid in the tubeless and I haven’t had any problems (300+ miles on this setup so far). I’ve heard that if you’re running Stan’s fluid you’ll want the valve stems that you can easily remove the valve to clean it out and refill it.
I agree with the weight savings that Bomb was talking about. I run 2.3/2.4 tires on my Kona and the correct tubes weigh a ton!
