Okay, so I bought this bike https://tinyurl.com/5rnlo3 and am replacing basically everything but the frame, not all at once but over time. So far so good... I am looking to replace the cranks and would like to put a vintage set of Campagnolo cranks on it. In its description it says:

Crankset: 3-pc Alloy, Euro Cartridge BB, 42T.

Question is... Will the square taper on there now work with the older style Campagnolo cranks? How can I find out short of buying cranks and trying them on?

Very very doubtful that it will work. Just get the right bb for your crank set. They aren't particularly expensive and will save you a lot of hassel in the long run.

In fact I have a loose ball Chorus bb from the eighties with a 111mm ISO spindle to trade if you want it. PM me.

You need a bit more info than that, namely

1- The spindle length of the bottom bracket
2- The style of taper (JIS or ISO)

then you need to find what spindle length your cranks need, and what kind of taper they accept (I believe campy is ISO but I don't know for sure so double check that)

Also, holy crap that thing must be a tank. Steel stem, seat post and bars?

Its not bad at all. I get lots of complements on it in Austin. I stripped everything off of it and it doesn't look too much like that anymore.

The idea was to buy a buy and change everything out, but always have something that was rideable. I will eventually replace the frame and sell it with all the crap I took off, but I didn't want to wait until I found the perfect vintage beater frame.

Stem is on my list, I already replaced the bars. Old campy seat post, brooks saddle, etc.

Not sure about the taper, I really think its ISO, but its just a guess.

How do I measure spindle length?

huerro

You can take the cranks off and measure with calipers.

I'll bet you a bottle of whiskey it's not ISO.

dookie

sez 'euro' crank, not jap. gotta be ISO...

Campy is ISO. Need a new BB. The centaur/veloce BBs are cheap.

just so everyone knows, this bike has a campy bb..

I'll pm you my address for that bottle of whiskey now.

How'd you figure that out

huerro

I'm not shipping it to Canada. Send me your paypal email and I'll send you the funds (once we know how he figured it out)

I just sent the question to the ebay seller.

i bought an old campy crankset as seen in this thread (https://www.bikeforums.net/singlespeed-fixed-gear/501640-campagnola-crank-question.html) three spoke 52/42. i ended up just taking off the 42 and the 52 sits flush. i took it over the yellow bike austin, and we put it on. the taper and the new arms sits exactly where the old one sat, in terms of mm from my frame etc.. cranked them on added some links to my chain and it was good, rode it about five miles home in the south. oh and just to be sure we also tried out a shimano jap. crank arm and it didn't fit the taper at all. i wish i could remember the guy that i was working with over there, it was last night..

I was just kidding about that but shipping to canada isn't that much harder than within con u.s - (I get this all the time from ebay sellers). I do the reverse and it's a matter of ticking an extra like 2 boxes to get stuff sent from here to the states.

At any rate the OPs test above in post #13 is too ambiguous to tell whether or not it's definitive. It certainly isn't to me. I mean a pre-built new bike having an ISO bb on it by default would be unusual. I'd like to start refuting the evidence one by one but i'm going to drink some whiskey instead.

huerro

I was more concerned with duty on booze...then I realized that it wasn't you I bet anyway.

I sent a pm to BD Mike. It is hard to imagine it would be ISO.
