What I mean is that resin pads brake immediately hard even with little power on the lever. Later on, indeed they do not resist as well to long braking like in downhill or/and an heavy bike.
But the problem here with this Tern is too much power when starting braking.
Therefore, I think that moving to semi-metalic is a solution with changing the rotor if the one mounted aren't made for semi-metalic pads.
