In the past I’ve always used 2.35″ High Rollers on all my bikes except my DH bike. But now I’m running 2.1 HRs with Exception (paper thin) sidewalls on one of my bikes.
The additional speed I get from these is great but I need to run them at very high pressures, 35psi front and 40psi rear to avoid pinch flats. When the tyres are spinning fast, grip is pretty good, but when things slow down and get technical, roots and rocks they’re as good as useless.
I love the light weight speed but the grip has just gotta improve. So:
-Should I just go back to 2.35″;
-Should I try a thicker sidewall 2.1″ at lower pressure;
-Should I try tubeless (ghetto) with the same tyres;
-Any other clever ideas?
What are you experiences?
