Hokay.
So you can get the 7600 Dura Ace rear hub in a normal 120x10mm axle, or 110x8mm ‘NJS’; or the parts to retrofit either way as the hub shell is the same in either config.
To me, the images I’ve seen of the 8mm axle look very much like a 10mm one, just with flats cut on it.
If so, can I take the 120 axle, the cones/locknuts from the 110 axle, combine and make a 110x10mm hub?
Much the same question re Suzue ProMax SB.
I’m piecing together a '90ish BMX and I want to build some super fast rolling wheels that are kind of period correct.
