I've been riding the newer 700 x 28 Grand Bois 'Cerf' tires for a week or so now, and really am pleased with how nice a tire it is. It's still a bit larger than my ideal, but for it's size it feels lighter, rolls really well and really sticks to the road. I believe Jan Heine compared the ride to a Clement 'Campione del Mondo', I'm thinking more 'Paris Roubaix', but that was a long time ago for me. The tread is razor straight while at speed, really a nicely put together tire. Running 92 x 95 lb's. in the fr./rr., they just about took out all the expansion cracks on my stiff RS touring bike and my hefty heifer body, with just a couple more pounds for my ideal feel. I've been looking for a nice gum walled daily rider now for some time. This is as close a new one as I've found.
Now if I can only convince Jan to try to get the Grand Bois' in a 25-25.5 mm tire for that 'criterium seta' ride!
Happy trails,
