i mean to the comment "DHF super tacky front and rear" I disagree strongly
I don't think these hold very well in the hardpack/dry over loose conditions very well.
They stick well on the roots and rocks but on everything else it seems less reliable.
Any experience with Ardent or highroller? Especially the highroller 2, I'm wondering how that rides
Then you should ask yourself if you ride them correctly you really need to lean on the outer knobs to have grip, there is a transition area between the middle and outer knobs on the DHF.
at least 80% of world cup DHers go for that combo front and rear and they don't seem to complain.
