I have done a search and cant find it specifically....soooo..........I know the 3500 crank has the steel variant but dos'nt this also exist with the 3400 crank and if so what are the markings?

Thanks

Stock Steel 3500 crank + machine shop = the steel 3400 crank you probably heard of.

So the markings are the same?

no, the 3500 crank is a different casting.. the 3400 crank has "981" cast into it..


Not sure where the "forged" 3400 crank that JBP used to sell came from, the 3500 crank is not forged.

Thanks.......thats what I needed.....they all are cast its just that some are cast steel and the"981" is what I forgot....

cheers

3500 crank is not forged.

Was that the final conclusion? It's weird that they have the wide casting marks like a forging.

I think so...

maybe one of us should take their crank somewhere for them to figure out...
