what cranks do i have??

i can't seem to find these cranks anywhere online. they have no markings on the front and the back simply says "170" then down by the pedal "9/16X20F"

they don't appear to be campy, or phil wood...

The "9/16x20F" is just the pedal threads, 170 is the length. The cranks look like 1980s Suginos, but I'd expect the brand to be cast into the back side of the arms.

My guess is fairly modern, Taiwanese. Andel, or lots of other brands, possibly....

Can you tell the bolt circle diameter? Or at least measure the distance between two adjacent bolts, center to center?

They remind me of avocet cranks that were made by Ofmega but not marked as such.

No chainring 'lands' or whatever they're called on the inside if the spider so they could be track or bmx specific.

I looked closely at the pictures, but I don't see anything that tells me that they're swaged.

I don't either, nice transition between the spider and the arm. Never seen that on swaged, but I guess it's possible

They look identical to these Ofmega Super Competizione http://www.velobase.com/ViewComponen...=115&AbsPos=88 except the pedal threads are not listed as Italian like the OP's (but Velobase does not have a check box for Italian so it has to be written in) and there are chainring lands. I would also look at the branded chainring for the likely manufacturer to confirm.

Edit; As suspected Ofmega used Italian pedal threads (I'll do the correction); I'm guessing the OP has a track version of the Super Competizione like these,http://www.ebay.co.uk/itm/NOS-OFMEGA...p2047675.l2557 and were reported to be Ofmega's copy on the non-fluted Campy Super Record (late 80's).

after a little more digging i'm thinking that's what they are as well.

sorry guys, this got moved over from SSFG, if i had posted it here first i would have clarified that they are, indeed, track cranks. and the machining on the back is certainly too fine to have been a situation where someone ground off the tabs for the second ring (is that what you mean by swagged?)

No, swaged means the spider or the ring itself is pressed on the arm with a huge machine. This is somewhat crude and not as nice as a fully forged cranks and is thus mostly used on low-end cranks (although Topline made a beautiful swaged crank).

ah, yes there is that interesting little lip on the back, but the crank is definitely one forged piece
