BOB JACKSON

With over 40 years of trend setting design and quality building, Bob Jackson is one of the world’s most famous names in custom frames and enjoys considerable popularity in many countries. Mr. Jackson takes great pride in being 100% flexible — ready and willing to tackle any custom design the customer desires. With 2 tandems, mixte, racing trike, tracks, touring and racing models Mr. Jackson is also one of the most versatile builders in the business. Every frame is made under the close and careful personal supervision of Bob Jackson himself. The Jackson painting, which has been copied by many, is his most famous trademark. Each frame is sprayed in several separate, time consuming stages then baked. The end result is one of the most durable and beautiful finishes in the industry. For 1981, we continue our two all-time best sellers, one for racing, the other for touring. Both are recognized everywhere; as finely made
