hmm... I might skip.
Components
The components used on the 310 varied throughout its several years of production, but certain elements were consistent through.
* Chromoly tubing was used for the frame. In early years, straight-gauge tubing was used[1], but this was changed to double-butted tubing for the 1982 model year. [2]. Starting in 1985, and lasting the rest of the production run, triple-butted tubing was used.[3]
* Early models use straight-gauge, hi-tensile steel forks. These were replaced with "Mangalight" manganese-alloy forks in later years.
* Most components, including the brakes, shifters, and derailleurs, were sourced from Shimano. The gruppo used change year-to-year, but later models used many Shimano 105 components.
* Certain components, including cranks and stems, were first-party branded.
