I don't actually think I've seen a Shimano direct mount to 64BCD adaptor. In saying that, I haven't been actively looking, as I went to a GXP style 24mm spindle crank ages ago, simply due to the number of readily available aftermarket chainrings in all offsets & tooth counts. And there's some quite light, very nicely made ones floating around for cheap. Try 550gms for a 170mm crankset. For around $70 AU.
Thanks again @speedygz
NICE!!
Which Fovno cranks would you be happy to use?
Do you have any issues with the Fovno style crank and BSA BB's?

What size chairing were you wanting to run? Shimano themselves go down to a 28t, in M8100.
28T is probably the lowest. I like the greater availability of offsets and tooth counts that are available using the SRAM chainring mount, and I'd like to use a Shimano chain (on some bikes), and it looks like I can do that. 😎😎

I've had a set of the Fovno Phantom 170mm cranks for just over 4 years now. Only issue I've had is the Aluminium bolt on the non drive side cracked on the shoulder of the thread where it meets the head, & I noticed the crank came loose. Ordered another bolt through Risk components, with a thicker head, 15mmX1 from memory, & it's been fine since. Been on 3 different bikes now, no complaints. 170mm is the shortest they go. I've also had a set of 170mm Snail SXX cranks, with the Shimano style split spline crank clamp interface for nearly as long, they're a little bit heavier -just over 600 gms from memory, as I think they run a steel spindle, but they've been faultless. And I've also ran a set of 165mm Deckas GXP style 24mm spindle cranks as well. Only issue I've had with them is that the self extractor cap unwound itself as I was removing them the other night, & I couldn't find the appropriate tool to wind it back in tight again. A block of wood and a tap with a hammer popped the crank arm right off anyway, no drama's there.

Lol lol. I picked up a set of Racework 170mm Shimano style 2x 104/64 BCD cranks a while back, as I have access to a Lathe & milling machine, & I was going to machine off the 104 spider, & then face off the 64 BCD mounting bosses to the appropriate chainline, 142mm non boost for my previous bike (the one in the photo). But I stumbled across a exceedingly cheap side swing front derailleur, & it never happened. Lol. As I was running the 11-46 M7000 drivetrain on it at the time, with a 26t chainring, which were really difficult to get a hold of here. You can actually run the 11-46 2X as long as you don't go over 10t difference in the chainrings. The side swing derailleurs are a revelation. Slick, smooth, light shifting, and quiet. Which was most of the reason I never went ahead with the crank mods.

With the Snail crank, & 26t GXP style chainring
