Does anyone know anything about this? it is a left 180mm 309-826-7791 beckyr469@hotmail.com

Never seen such design!
Must be home made to use on a home made spindle......

sure doesnt look modified to me, maybe a prototype of some sort, I'm sure the Hutch guys will be all over this thread in a couple of hours...

maybe it's a early version of the Sanderspeeds, before he realized they were pinchless...

is the other side the same?

If you look up in the BMX Museum at the top of the page, then look under BMX parts, there are a set of prototype Aerospeeds that have a double pinch bolt. So I guess it could be possible.

looks like it might have been cracked and someone tried to repair it???

Those are the real deal. I have seen 3 of those arms in my life time. One set was about 100 miles north of me. Came right from the old hutch stock pile.

So they are real hutch proto type cranks?

Only thing aeros have going for them is good looks and that just kills the look of them for me.
