I recently picked up, for free, a SOMA Generation bike, probably from late 70s/early 80s. Its missing pedals. Does anyone know if the pedals for this bike would be of 1/2" or 9/16"? I can always do trial+error, but I'd rather save myself a trip to the store if possible.

It has "Alero Cold Forged" cranks on it

Look on the crank arm. It may be stamped there for your edification.

Sadly no luck, I'll jsut do the trial and error way next time I'm by the bike shop

Should be 9/16".
