BMXmuseum.com Bikes / Campagnolo Racing

NOTES:
Typically the development of Campagnolo parts was carried out with the help of professional road and track riders on teams sponsored by Campagnolo. For this reason, Campagnolo parts were in use one or more years before they were ever offered for sale to the public. Campagnolo parts could appear in stores or on bikes before ever appearing in a catalog or, on the other hand, were not necessarily available at the time a catalog was issued. The catalogs were typically printed for the trade shows which occurred late in the year (the Milan bicycle trade show was held biannually, odd numbered years). Therefore dates established by a part's appearance in a catalog are, for the most part, approximate.
