I'm not convinced by that argument myself. Considering the diameter and depth of the respective pawls and bodies I'd say the actual contact areas are probably pretty similar... As has been said many a time, until someone who can actually ride trials properly gives the I9 a go and provides some feedback I'll be unconvinced. Especially if the best evidence that comes up is that they work brilliantly for XC, freeriding and BMX. Different. Kettle. Of. Fish. And what a weird saying that is...
