Here is a bit of an update after a couple more days ride. I am now running with 15psi cold.
Completed 440km now. The first post after 135km was fairly tame riding really.
Yesterdays 200km was alot more aggressive riding with lots of rocky sections.
Just as a comparison, the 3rd photo is my brothers D908 with 3000km on it, same bike, same tyre pressure. Similar rider etc. Think I know which one I would go for next. Maybe a different result in flat desert riding but when there is lots of hills and rock involved I wont be getting onother one. I would love to know how the MT21 would have handled it. I cant see it being any worse than the mitas. Oh and did I mention it doesn't do well in the mud
