Was wondering if anybody knew if there was an appreciable difference between record 10 and chorus 11. And if so, what it might be?
Not counting the cassette

Thanks

I'm going to say that the cassette would be the only appreciable difference. Record 10 with UT cranks slightly lighter, but not very much.

Record '08 vs Chorus '15 (spec):

RD 184 vs 183
FD 75 vs 76
levers 324 vs 350
cassette 188 vs 230 (Record all Ti 156)
crankset 643 vs 683
chain same weight
brakes 279 vs 321
cups 49 vs 46 (they reamed out the newer cups more)

Total difference of 146 grams. Even without the cassette the difference is over 100 grams which for weight weenies is about 5,000,000 drillium holes....

I had a diatribe about the new brakes before... being heavy is only one of several give-backs of the new Chorus brakes.
