There are a lot of factors when it comes to tires. These tires meet all the criteria. They're sticky and super fast at the same time. But what sets these tires apart is their reliability on wet roads. I know these tires will keep me upright in the rain. Period.
I've been training and racing with the CS-7900 for two race seasons. I push all my equipment to the limit, and I did the same with this cassette. It's always smooth and precise, regardless the conditions or wear.
