Subject: RE: Michelin KrylionsI don't have a ton of experience with many different tires, but I have trained and raced with my Krylions for a little over 1000 miles. I don't want to say never a fl@t yet because I don't want to jinx myself, but knock on wood, they have been sturdy. To me, I don't notice the difference in rolling resistance from the tires that were on there before. They are so much cheaper than GP4000 and I think the resistance is less than that of Gatorskin, but don't quote me. |
