I have done both steel and Ti versions of the Superleggeri pedals , I’ve only had one set of GS pedals . The only ones that were a bit challenging were the Ti spindle pedals , because of the tiny freaking balls! Sp rewarding though , to have buttery smooth pedals . Once done , they should last for e very long time . The last set , on my Colnago that is my main ride , I just checked after having a dust cap fail ( plastic was cracked at the threads ) . It had been since Eroica a few years ago and they looked just as if I had done them yesterday. Good job on the instructions , I have the Campy wrench that has the lock nut cut out on the opposite side of the dust wrench and it is very handy.
