Hello and thanks for checking out this new Campagnolo Record CT 35mm clamp-on front derailleur. I discovered a nice batch of these front derailleurs in the collection of a fellow cycling hoarder. Each will come to you in the true “NOS” new-in-box condition seen in the included photographs. For clamp-on applications and 35mm seat tubes. For use with 10-speed compact double cranks and Campagnolo 9 or 10-speed mechanical shift levers. Please see the included pics of the part you will receive. Increasingly hard to find… Perfect for your modern classic build! Contact me with questions, I will do my best to answer them.
