This Imperial Mark II is fairly typical of the bicycles CCM produced in the 1920s – 1960s. Probably the most obvious trait shared by these bikes is the curved top tube. While this was primarily a stylistic trait (exemplified by the CCM Flyte), there was probably a practical element as well – the curve could be varied to accommodate different frame sizes and geometry, while using the same lugs. The components are another distinguishing feature of these vintage bikes. Unlike modern bicycles, which may have parts from a dozen different manufacturers, CCM produced all of their parts in house. This lead to great details, like the logo pressed into the crown of the forks (middle) and the distinctive CCM chain ring (bottom). Designed with minimal complexity and without concern for the final weight, these bikes are super durable. After decades of heavy use, many are still going strong.
