Ardent 2.4 if it'll fit.
Nearly every clincher rim/tire can go tubeless with the use of tubeless tape, tubeless valves and sealant. The Specialized Captain Sports (assuming you have the Rockhopper Comp) are not 2bliss ready, but that shouldn't effect them going tubeless. Overall, going tubeless would work out better for you especially if you have a lot of roots and rocks for pinch flats.Vampyre said:I am not running tubeless, i have thought about it, read a little about it. I am running the stock rims from my 2010 rockhopper 29er expert, so I will have to see if that is possible.
I typically run about 35-40 PSI in each.
I don't recall the widths, Nevgal I believe is 2.2", and I think my rear Specialized Captain is 2.2' also
I have a 29" bike, so it limits the sizes...
