| Group Family General Info: Shimano Dura-Ace was introduced in the mid 1970's as their flagship road racing group. While their early generations often found itself on a very wide range of bicycles, by the 1980's the group was starting to make a name for itself as a true competitor of Campagnolo's Record group. |
| General Info: The Dura-Ace 7500 group is a track / fixed gear groupset produced by Shimano at approximately the same time as their Dura-Ace 10 group. The 7500 series however did not use the 10-pitch design, but a standard chain and tooth size. |
