I'm guessing no, but figured I'd ask.

I have a pretty much brand new pair of Fly cranks. Anyway I could run these on a frame like a black market or something?

Yes. Buy a BMX Euro BB. Not hard to find, really. Orrrrrrrrrr....



Take a Shimano/RaceFace X-Type BB, and pry the bearings out. Then pop in a Spanish BB (OD of the bearings is the same), run the dust caps, and play with spacers for chainline. I think the first option is cheaper and easier.

so I can't run an outbound (not sure of the correct name, bearings are on the outside of the BB) BB?

The bmx euro bearings seem pretty tiny.

might be a tight fit or not work at all. fly spindles are short (i think 5.75") you may need 6" or more to set up a blk mkt or similar mtb frame.

I ran them on my GT Ruckus UF 24 for a while with the Eastern Euro bb. The bearings were pretty itty bitty, but it worked for a couple months until I got a new frame.

Yes, you can do it, but be prepared for possible issues with the bearings. The 22mm spindle means that the euro bearings will be super thin. I ran Wombolts (also 22mm) on a spanish bb for awhile and I had some issues with the bearings... euro would be even worse.

Hmmm.

Anyone want to buys some pretty much brand new, 170mm Fly cranks?

As mentioned above, but with pictures. This is an option if your spindle is long enough.
