Established in Italy in 1939, Olmo are still producing bicycles today, however their heyday of technologically advanced, lightweight race winning bikes was through the 70s and 80s. Guiseppe 'Gepin' Olmo was a very quick rider in his day, at one point holding the hour record, and as was the standard career trajectory of the time once he retired he started a bike brand bearing his name. The Olmo company grew quickly and diversified into other industries through the years, and whilst they produced a large number of bikes they were responsible for building some incredibly high end ones too.

The Olmo San Remo appeared in the mid 80s as a more value for money version of their absolute top end race bikes. Made in the Olmo factory alongside the bikes they were building for professionals at the time, the San Remo featured a double butted Columbus tube set, chromed forks and rear end, and was available in a choice of paint schemes. This frame is probably from the late 1980s and features a wonderful Mondrian influenced primary colour on grey paint scheme.

If you're taking part in L'Eroica or a similar vintage event, this frame is of the correct age, so you won't be disqualified for being a rule breaker!

The frame's been carefully checked by one of our mechanics to confirm the alignment's correct and there's no damage to the threads. If there are any minor issues worth noting we will do so in the overview section below.
