I’ve run rocket ron clinchers tubeless on Mavic CXP 33’s without too much trouble.
I needed to go to the garage across the road to get the bead to seat, and it took a couple of nights of adding sealant, spinning, leaving overnight and topping up to get the sidewalls fully sealed up. But once sealed they were great, burped the rear once during a race but still had plenty of pressure to finish (without having to slow down).
Defo saved me a DNF at least once, juding by the sealant spray up my back at the end of one race!
Would be interested in other’s experiences, as was thinking I’d need some more mud-specific tyres and wasnt sure what would work well…
