The Dominators aren't technically tubeless. I suppose ghetto technique is always an option. I've decided I hate tubeless though, and am reverting to tubes on my bikes that are tubeless. On my Susie, I used some of those new-at-the-time polyurethane tubes from Tubolito, to save weight. I can't technically endorse these because they're not supposed to be used with rim brakes. But, once again, I've had no issues and am super happy with them. I just don't bomb downhills where Id generate high brake temps.. It's a joy to NEVER have to pump up your tires... in contrast to tubelss where I have to do it all the time. I figure the bigger volume helps dissipate heat, too.
