  • Olmo-stamped Magistroni cottered crankset
  • 51/48T close-ratio racing rings
  • 170mm arms, chromed steel
  • Complete Italian thread BB, 36×24, 70mm shell
  • 132mm spindle e-e, cotter pins included
  • Includes: arms, rings, BB cups, spindle, lockring, bearings, hardware

Condition: Very good condition. Chrome is glossy and bright with patina toward the pedal ends of the arms. Teeth are in fine shape. Some patina on the spindle. BB threads are in great shape. Bearings cleaned, all balls accounted for, will need regreasing before install. Lots of miles left.


Notes from MyBikeThing: The real deal — Olmo’s own stamped crankset off a 1950s-60s Olmo that came apart without a fight after sixty-plus years. The 51/48 close-ratio rings are pure period racing spec, the kind of gearing nobody has made in decades and Eroica builders hunt for. Sold complete with its matching Italian-thread bottom bracket — the pairing this crank was built around.

Workshop Wisdom: Italian bottom brackets thread right-hand on both sides — the fixed cup can loosen under load, so install it tight with a thread compound. And press cotter pins in, don’t hammer them; a bench vise with a socket seats them clean and saves the threads.

Guarantee: You put in the miles, we put in the work! 30 day Guarantee, rest assured of fit, function and condition 🙂
