Does anyone have any experience with these tires. Im looking to try something new, and on paper these tires look very nice, similar to there tubulars. But I have not been able to find any reviews or opinions on these tires. Has anyone road them?? thoughts comments on them?? I have been riding Michelin Pro race and Vredestein tri-comps for the past two years, so im looking to try something new. All help is appreciated.
