|My 81 Medici Strada still has the original Record Crank and that 42 took it's toll in a steep Century yesterday. I'd love a 39. Do I have to get a Chainring from the 80's or will the new chainrings work?|

|chainring that you can use due to the large 144mm bolt circle on old campy cranks. You would have to get a newer crank to get a 39.|
|I guess...||Berkeley Michael|

|anything I do to make a conversion means a new crank or new der or new cassette and new der or new drivetrain or spreading the rear to accept the newer line of drivetrains. I'll just deal.|

|Someone, not Campagnolo but I don't remember who, made a 41 tooth chainring for these cranks, but I have no idea where such a thing could now be gotten, and that isn't much of a change.
Keep checking that crank for cracks. The old Record cranks have a tendency to fail near the base of the drive-side crank, where it joins the spider. I've also heard that they can break at the pedal hole. Actually, when mine broke it was a blessing in disguise. I replaced it with a fine-looking retro Shimano 600 crankset that takes a 39 tooth ring, and thus don't have to "just deal" quite so laboriously up the steep hills, while being relieved of the guilt of tossing a classic Campy crank.

|I can tell you for a fact that a 41 would have been welcome at about mile 80 of that Century but it doesn't sound practical.
Your suggestion of a Shimano 600 Crank sounds pretty good though. Any further info on that?

|In fact, Campagnolo DID make a 41T inner ring, but only in Nuovo Record, not in Super Record. It can often be seen in photos of TDF bikes used on climbing stages instead of the "normal" 42T SR ring. The 41T never appeared in Campag catalogs; you had to know it existed and order it. I have one on a period Casati.
Numerous other people made 41T rings ie Ofmega, TA, etc, etc. The TA rings should still be available from Peter White or Sheldon Brown...

Not a huge difference from the 42T, but a difference just the same.
|Wow! Thanks. nm||Berkeley Michael|
