The new in box Campagnolo Record Ultra-drive Ti Cassette CSK00-RE1013T 11-23 is a high-quality cassette designed for Campagnolo freehub/driver type bicycles. Made of durable titanium, it features a 10-speed setup with a largest sprocket of 23 teeth and a smallest sprocket of 11 teeth. This cassette is perfect for road bikes, cyclocross bikes, and racing bikes, offering a sleek design in titanium and silver color. Made in Italy, this Campagnolo cassette is a top choice for serious cyclists looking for precision and performance in their cycling components. This is great stuff from a great company, this is new in box, never been used. It would be a great addition to your bicycle with a worn out drive train, I bet you are tired of all the slipping and skipping your clapped out cassette is doing. Feel free to ask questions, I will answer to the best of my ability. I will only ship to the continental United States.
