I found the 26x2" acted like a brake when I stopped peddling!
Great for my Pamir Highway trip - no issues at all.
In fact there is still plenty of tread left on them and I have listed them for sale here.
Horses for courses I guess.
All my other tours have been on 1.25 or 1.75
Schwalbe Marathons. Only one puncture in Morocco. Sri Lanka, Ethiopia, Thailand twice - all good.
But interested in others thoughts.
