I found some reports about GrandBois tyres but very little if anything on Col de la Madeleine in 23mm ones.
Unlike others there are the most sportive ones whereas most others are wider more touring ones.
I was thinking about these for they seem to be wildly lightweight, wildly comfortable, and wildly supple.
I was wondering whether this suppleness would not be against performance and durability.
Any feedback on puncture resistance?
