I ran 29in CMs front and rear on my Inbred. Unfortunately, the rear was a little too big, so i had to replace it with a Smorg instead. I’ve not done huge amounts of riding with them, but they seem to work well, and they hold up very well at a low pressure (currently 18ish psi in the front, 15 stone rider on a rigid bike).
Contrary to the above, they’ve all effortlessly inflated tubeless with a track pump. In fact the CM i briefly ran on the rear inflated just as quick as it would have done with a tube. (Velocity p35 rims, if that makes any difference)
