Hitchy said:G'day all,
a mate has been told, (by his LBS),that in order to change his Chorus 10
cluster from 11-23 to 12-25, he needs to buy a whole new cluster. Can he
just buy the individual cogs that he needs?....being a died in the wool
Shimano man, I have no clues on Campy stuff. Any help would be
appreciated,
He doesn't need to buy a complete cluster. There are charts on the
Campag website that show exactly which cogs and spacers go to make up
each cassette.
Briefly, he'll need a new 12, 16-17, 19-21, 23-25 plus new I and L
spacers (1 each), plus maybe a new lockring. The new 12 has ridges to
fit with the lockring. In the 11-23 Chorus, the 16 cog is a single,
and the 17-19 and 21-23 cogs are doubles.
The next trick is to find someone who stocks the parts.
Centaur and Veloce cassettes are cheaper, but a bit heavier.
