I am going to go from record8 to chorus10. Anyone know the weight difference in the group itself?
try here for the nitty gritty differencesCT1

My guess is that the difference is probably in the 50gm range. Probably depends more on the cassette type and size than anything else.

The C10 stuff, both Chorus and Record work the same. I.e. perfecto.

but I think he is asking about 8-speed Record to 10-speed Chorus, making the difference rather more pronounced than 50 grams. The rear hub alone is 120 grams lighter with 10-speed!

My point was that you should NOT be converting to C10 Chorus to "save weight". Even if the weight difference was 200-300 gms that doesn't seem like a good reason. IMHO, if you want more gears and newer h/w ..... well those are logical reason for a h/w swap.

just my $0.02

My primary reason for the swap is more gears but I was curious to see how much weight was saved.
OK then..... here is my suggestion on gearsCT1

If you cherish close spaced gears but also need hill salvation get a 13-29 and replace the 13 with a 12:
12, 14, 15, 16, 17, 18, 19, 21, 23, 26 This will give you the beloved #18 which is quite nice when hammering.

You can also build custom C10 cassettes by mixing/matching cogs from other Campy drivetrains. That's how I built a 12-23 near straight block. Same as above except swap the 13 for the 26. :-) This will require machining down some of the 9 speed delrin spacers though. I use this cassette almost exclusively.

good rides to you
