I'm fairly early on into the lifetime of my Duranos, and so far it's been OK
(don't tempt fate!
)
The main issue for me, on my road bike, is clearance. Marathons come only in sizes from 25mm up, and I must have no bigger than 23. I once fitted 25mm's (Armadillos) by mistake: the front was touching the fork crown and the rear was almost fouling the seat tube - a little bit of dirt on the tyre and it would make contact. So for me, Marathons are no-go on the road bike.

i thought we are talking about tyres here. so let's say m+ tyre is heavier by 320g (than half decent 25c tyre with p-protection). that's 640g extra where it matters most. matters to who? probably not me, as i will be getting another set at the end of this year.
