hi, i picked up an older DA bottom bracket (NJS stamped, so i think it's the keirin BB, but i'm planning to use it with a road double crank), it's the style with the fixed cup, adjustable cup, and locking ring.

the bb didn't come with a spindle, and finding DA spindles is proving hard, so i'm wondering if the Ritchey Super Logic BB spindle linked below will work on this BB.

any ideas?

All dura ace bb axles I have gotten even for road bikes are stamped njs.. even the cups are certified also.

The dura ace spindle should be a 68x112, and I believe is symetric... hope this helps better.

Which cranks are u going to use??

I thought the old Dura-Ace spindles were actually asymmetric.
