Couple that with all of the new parts you have to buy you could probably purchase another bike to ride with brand new SRAM rival or Shimano Ultegra and keep the cool old school bike original.

but either way good luck and ride hard!

8 speed road hubs have been 130mm since they were introduced. 10 speed road hubs are still 130mm. If the bike had 7 speed hubs, it might be 126mm but even then, it's easy to spread the rear triangle that 4 mm by hand without setting the frame.
