The day I put my EXOs on I had 3 flats within about 3 kms. Rear flat, front flat, rear flat...Used up all my tubes and emergency sealant and walked out.
This is riding fast and rocky stuff. Plenty of pressure, good rim tapes, deliberate line choice to try and avoid the worst of the rocks.
Carcass holds up well for cornering, grip is akin to a DH minion, but start ploughing bigger rock sections at pace and they fall to pieces. I threw one out, after one ride, because it was full of holes,like hold-it-up-to-daylight-and-look-through-it pinholes.
Great trail tyre, just be cautious in extended, fast, gnarly rock sections I think.
To be honest my LUST casing High Rollers were a more reliable tyre.
