My Amflow PL Carbon Pro was produced in Aug 2025. I now have 1,700 miles primarily riding rocky terrain in the desert southwest. I have not changed anything except tires, new sprocket and a new chain, everything else is stock. Thankfully I have no cracks on the seat tube and I suspect if it hasn’t happened by now it probably won’t (I hope).
And for the person who thinks you can buy a well kitted M1 Amflow for $3K, I have a bridge in Az I’d like to sell you . Everyone wants an Amflow but none are available, so trust me if someone has an M1 in great shape they will get WAY more than $3K.
