Every cyclist knows Shimano 105 as the go-to groupset for value and performance. But many riders still ask: how old is the Shimano 105? Understanding its history helps explain why it’s still one of the most trusted choices today.
The Origins of Shimano 105
Shimano 105 was first introduced in the early 1980s. It was designed as a mid-tier groupset, sitting between Shimano’s entry-level offerings and the professional-level Dura-Ace. Over the decades, it has consistently delivered a balance of affordability, reliability, and technology.
