Grand Bois Ecureuil Extra Light - 650B x 38
Fast rolling, light and supple tire.
The "Ecureuil" is the lightest rando tire, tipping the scale at only 240g for a 38mm width.
It is the perfect tire for fast paced yet comfortable "brevet randonneur" or "fleche" rides.
Of course, due to its extreme lightness, this tire is not meant for heavy off-road or trail riding, but it will certainly make you fast and save a lot of energy on rough tarmac and smooth gravel as it will dampen all the vibrations, allowing for a faster pace than with over inflated narrower tires.
