|Swapping a Campy 42 for a 39......||Fausto|

|Going to swap my inner Campy 39 ring for a 42. From what I understand, technically speaking the two front rings are "phased" in together ( at the factory) to faciliate smoothe shifting.
I also have been informed that this is no big deal.
When bolting on the ring, what do I look for in terms of the orientation of the inner ring ( position wise ) ?
Rule of thumb for tightnening the bolts and crank.

|I just swapped out my record 39 for a 42. No problems, the shifting is as smooth as it gets. As for aligning the rings, just match up the the little rhombus-looking etching on the 42 with the one on the 53. As for the tightening procedure, I was very careful not to overtighten the hidden crankbolt from the back. Also, I noticed that the factory did not apply any locktite to the other four bolts. You might want to do that befroe tightening. The blue stuff wors well.|
|Make sure you get 9 speed or 'C10' to match the rest (nm)||Spunout|
