Are they doing you a special? Normally their A 7 cranks are from forging, not billet
Yes, it is a special. Current Phoenix A7 cranks are from forgings as you say; Some earlier A7 Phoenix cranks were investment cast and then HIP treated. I have a 1 1/2" version of those here.
If I understand your reply correctly yours is from a casting , in which case it cannot be a billet crank.
A forged crank is better than a cast one, interested to know why you would be using a casting.
Just to clarify, I have an early run-of-the-mill Phoenix 1 1/2" crank here -these were investment cast, and then HIP treated. Phoenix later went over to forging for these cranks. I am also having a one off "special" crank made by Phoenix at the moment, they're making it from EN40 billet which will then be nitrided.
