We converted Kurt’s Santa Cruz Nomad to tubeless recently. He seems to suffer considerably more flats than I do so he’ll hopefully benefit from the switch significantly. We used Stan’s yellow tape and Stan’s valve stems with some environmentally friendly Blue Seal tubeless tire sealant we are testing out. Kurt’s Chunder Control tires are tubeless ready, but his Mavic rims are not made for a tubeless tire. Regardless setting them up was reasonably painless with the use of a CO2 cartridge to get the bead to seal [floor pump didn’t work and I don’t have a compressor]. So far they are holding air pretty well. I’ll be posting a tubeless update at the end of the summarizing all of our experiences running mountain bikes without tubes. Thus far I have no regrets!
