I'm wondering if should I go with road spacing @ 130 or track @120
FWIW, most track bikes use 110mm. Most SS/fixed hubs just need a few spacers, or maybe a longer axle nut. Suzue hubs just need spacers. The real
hardcore hubs may be a problem, though....
As far as I know, nobody makes a 130mm-specific SS or fixed hub. Just the plain old 120-126 hub with spacers.
