Stealing an image from the BMX museum page above, this is the BB my setup runs with. The outer race id threaded with flats to install into to a threaded BB shell. Open to the elements.
You can see it came with a myriad of washers to adjust the chainline with

Interesting. I guess some of them are not used?

Another question... What does this do? http://www.retrobike.co.uk/forum/viewtopic.php?t=158449 As I can't figure out where it goes

Hi,
Its kind of a safety feature, it goes straight throught the axle and should stop your crank arm from falling off, if the pinch bolt was to fail.

Used to see them back in the good old days of bmx racing.

Perfect. Difficult to tell from the first picture in the other thread what the scale was but these pictures are great, thank you.

I have received a crankset from USA this week-end.
I have to strip the ugly glycero paint on it, and the spider is now shining.
But I would swap the bolts which fix the spider on the steel circle of the arm. Who know what size they are (diameter and thread…)
Nothing is fitting in all my bolts boxes and I think it's an US size…
:D

Watch the bolts on the Bullseye stuff, it's all Imperial pitch....

The small clamp bolt often gets replaced with a metric bolt and this kills the threads, same goes for the spider/crank arm interface and I would image the same on the Gen 1 spider mount as well
