I want/need a new FD and RD for my Peugeot PX8. The FD broke and I am currently using a Raleigh FD. I was going to purchase a new simplex one, but they cost more than what I am willing to pay for plastic and Simplex SLJ is way too expensive. Since I am going to ride this all the time I wanted to have a decent groupset close to the vintage of my bike. Would the RD in this set work with a 10 speed and, if not, what group would you all recommend?
