650B Elephant National Forest Explorer

And you can't compare a Confrerie tire and a Grand Bois tire, it's like to compare a Michelin Dynamic and a Veloflex.
I get a pair of Grand Bois Cyprés Extra Léger 650b next week, I will give you the true weight.

I've never had any Grand Bois in my hands so I can't compare them.
It might sound naïve, but what are the main differences between the Confrerie and the Grand Bois (that could explain such a strong statement ...).
BTW, it's Cyprès, not Cyprés ;)

@Ed : In my experience, the Confrerie are not very puncture proof, but (again) I don't have enough experience to compare as I maybe rode about 2000 km with them and they're my first 650B tires. Only had cheap 700c stuff before...
