STD/STD 66 & 70.4 crank values
 

I know the answer is whatever someone is willing to pay...That said, what is the approx. value for these Cranks individually these days?

The 66mm crank is now 45+ years old. To find a Std/Std 66mm crank today is very rare IMHO. Great crank, spins up to 8000 + rpm with mods. I would think $900 to $1200 for a good Std/Std would be a good price.
The 70.4mm crank is getting harder to find in Std/Std condition today. More of these cranks were made so it's a little easier to find but most of the ones I've seen need journal work. They don't spin up to 8000 rpm safely with out a lot of work. Also rod bearings from Glyco have been a problem so the optional Clevite 77 series are the best choice but cost $$. I would think $650 to $900 would be a good price IMHO.

Prices have gone up Mark!
2.0 counterweight start at $1600.00
2.4/2.7 start at $1200.00

Well I was afraid of that. As soon as I hit the send button I had seconds thoughts on my pricing. Wishful thinking because I'm looking for a good 70.4 early crank.
Thanks for the price update Aaron.

I'll keep an eye out....i remember when they were 350 bucks....

I was trying to sell a good 2.7 core with a polished/inspected/magnafluxed std/std crank for $1200 about 5 years ago with no bites.
I'd like to what it's worth now....but I'm not selling it. For now it's my back-up plan if I ever had a problem with my 3.0.

I just bought a std/std 2.7 crank that was polished/inspected/magged for $575 on the S registry. Sure, there are some that sell for $1,000 but many sell for less than that. If you're willing to wait for a while and monitor the forums, you can find a deal on one. If you need one now, then you might be looking at the $800 - $1,000 price IMHO.
