Haven't had them off-road yet, but today was the first pavement ride with the Kenda Kross Pluses on my MTB, and I have to say I'm fairly impressed. I saw about +1-1.5mph over a section I ride frequently (compared to the CST Caballeros that were on the bike before). Decent enough ride at 65psi, predictable handling. I felt quite confident in the grip on pavement; off-road may be another story, but so far, so good.
