Campy strada cranks...no # on backside?
just won these on ebay...but looking at the photos of the back of the crank arms, they say "175 STRADA", isn't there supposed to be a date stamp number inside a diamond or circle as well? were there any made that had no number? did i buy fake cranks? i also noticed that one of the flutes on the spider has a milling imperfection. i don't really care about the looks, but will that compromise strength? here's the link to pics:

I believe the answer is that the crankarms date from 1968-72 before the introduction of date coding (they're likely earlier than the chainrings and predate the intro of super record.)

The rings are later than the arms, which PS is correct on the pre '73 dating. Is the inner ring a Campy ring? At least the outer is.
(I rode my old Record cranks around with Specialized rings that mimic the no-web SR rings myself)

i have some brand new TA rings to put on there; i'll probably sell the ones they come with.
ok, so not fake or anything, just old. they seem in pretty good shape for being that old. i guess i'll see when they come in the mail. thanks for the help!

I'd suggest using teh Campy rings as long as they last. If I recall correctly the TA material is much softer and less long-wearing than the Campy.

Nice Buy!
I'd keep the original rings until they wear out too.
Those simplex shifters are classy as well!

Be sure to check the old campy spider for the beginnings of cracks at the joint of the spider arm and body. Sometimes you can see the tiny cracks just beginning to form (hopefully) and can file them out a bit to end the cracks future career.

The 1972 cut-off date only seems to apply to the 170 length. It would seem that the rare at the time length of 175 were not produced with a date code until some time later, perhaps as late as 1977. This could mean that Campagnolo was already sitting on warehouse stock from the time period prior to 1972 or simply didn't date them. Lets get everybody check their 175 mm cranks to see what the oldest date code that we can come up with.

interesting...yeah, i'm pretty excited to get these. i've got long legs, so the longer crank arms will be nice. plus, the campy cranks i have now are pretty beat down...i figured i should get some that don't look like they're about to break.

Not to highjack, but do you really think you will notice 5mm difference?
