In reply to neuromancer:
You are certainly an outlier based on my and my friends experience of EXO casings.
It not a POV/opinion, it's that they have literally always failed when someone tried one, once things got chunky. We all ride both hardtails and FS, all across UK and Europe. No ebikes.
Raced many enduros, including Grizedale x6 and Graythwaite x2 in the Lakes; exo casings wouldn't have lasted a stage for me.
Never had a tyre failure in three seasons of racing PMBAs - saw a lot mind, probably all those EXOs, lol.
