This was a first for me....Changing a broken carbon spoke on a set of Mavic Cosmic Carbone Wheels. The spokes were very different (ran the whole diameter of the wheel) and you had to almost completely remove the tension from the wheel and rebuild it in a way. I replaced two spokes (which is actually 4) and had to completely retension the wheel. It was very interesting how the wheel was built and designed....an over, over, under, under cross pattern. This was a fun project. I love wheel building and playing with stuff I've never worked on before. Mavic has some very cool and durable wheels...check them out.
